Green laser technology from the watch industry first began its application

Green laser is also called stereolithography technology, its principle is the computer control laser pens on the surface of the photosensitive resin as raw material by point by point scanning, scan area resin thin (about a few tenths of a millimeter) to produce light polymerization and curing, forming part of a thin.Blue laser pointer down a thick layer of the distance, so that the cured resin surface and then deposited on a new layer of liquid resin, burning laser pointer scanning process, the next layer is repeated until the entire prototype is completed.

Because the green laser reaction is based on the interaction of light and not based on the action of heat, so the work only when the low power laser pens. Blue laser pointer other models including blue, portable laser marking machine, laser marking machine, CO2 laser marking machine, laser marking machine, CO2 portable laser marking machine assembly line laser inkjet printer, bar code, two-dimensional code marking machine, production date and batch number serial number of laser marking machine burning laser pointer.

Usually a small crack will cause the glass to break. Once the micro cracks formed in certain parts of the glass, it will spread to the edge of the glass, the fragile.Green laser rupture properties make it difficult to machining. On the other hand, the continuous development of the technology of the structure can be made smaller, and the shapes of the glass to be used in different fields. The precise of traditional methods, such as laser pens and blue laser pointer for processing glass, but these techniques are too expensive, difficult to operate, especially the use of a large area. Today, burning laser pointer provides the most accurate method for glass processing.

green-laser2

An exciting alternative technology has been put into industrial application, using the green laser sub picosecond pulse in the near infrared wavelength range. In this method, most of the surface or ultrashort pulse tightly focused on the glass, the power density per square centimeter number more than TW, lead to process complex, such as laser pens,blue laser pointer and avalanche, due to the highly localized damage to the glass matrix, and there is almost no energy deposition of burning laser pointer.green-laser4

Atmospheric green laser communication is a kind of wireless communication, which uses optical signal as the carrier of transmission information.

Because green laser is wireless communication, it can be moved to any location and mobile communication, which is its biggest advantage. Military value and concept in terms of atmospheric transmission of laser pens is very simple, that the laser beam will be transmitted to the receiver can use the transmitter. However, in the actual blue laser pointer, burning laser pointer narrow beam is required to receive accurate, so the system should also include the active alignment device.

In the space of transmission, green laser system must have a strong ability to remove stray light, or the sun or other laser pens laser beam irradiation will be flooded. In practice, the need to add narrow band-pass filter, can choose to receive the laser wavelength but not other wavelengths. The laser atmospheric communication system is the key practical technologies involved. There are continuous wave high power blue laser pointer technology; adaptive zoom technology; optical narrowband filter technology; burning laser pointer frequency stabilization technology.

Compared with the traditional means of radio communication, green laser atmospheric communication is convenient, easy to use, very suitable for the special terrain, the landform and the wired communication is difficult to achieve higher requirements and mobility in the workplace. In addition, the atmospheric communication system laser pens compared with other radio communication means, also has not occupy valuable blue laser pointer, burning laser pointer. electromagnetic compatibility is good.

The application of green laser atmospheric communication in military field is very wide, can stand in communication between high mountains and forests to complete the border post observation; laser pens can solve the temporary erection necessary communication and computer network or as a mobile communication switching station; blue laser pointer can be installed on the coast, rivers, the realization of burning laser pointer secure communication the island or the ship.

Green laser using solid laser or laser diode as seed injection type power amplifier structure

Effect of green laser nonlinear effect, these laser pens output pulse quality and maximum output power were restricted.Blue laser pointer developed a new alternative technology, namely seed light with mode-locked vertical external cavity surface emitting burning laser pointer 500 FS output, and then amplified to obtain the pulse width of 110 FS, nearly transform limit the average laser output power of 53W.

green-laser4

With the use of green laser or laser pens as seed injection laser, emitting laser using a mode-locked vertical external cavity surface as the seed injection of ytterbium doped fiber amplifier, can be produced with high power and nearly transform limited pulse laser beam quality.Blue laser pointer laser output from the power amplifier and fiber end injection pump on the light, through the power amplifier fiber ends of the burning laser pointer.green-laser2

Especially the application of green laser and laser pens in recent years, the formation of solder bump remelting temperature continues to improve, continue to use the whole heating method will make the package temperature and packaging device of large deformation and failure of the late assembly and in the process of service. Because blue laser pointer has led to high power density and excellent direction and local heating. Burning laser pointer, which has potential advantages in forming arrays of solder bump.green-laser3

Green laser is the idea of.Laser pens from the laser soldering and can be connected to form a highly concentrated energy density of blue laser pointer in a very short period of time, the package will not produce thermal stress, thermal sensitivity of strong burning laser pointer will not heat shock.green-laser1

Green laser ultrasound has high temporal and spatial resolution due to light source flexibility.

Green laser is a nondestructive measurement of residual stress of a new method of.Laser pens theory and experimental results show that the existence of stress in the workpiece, laser beams in isotropic elastic body velocity and no stress when the transmission speed is different.Blue laser pointer related to the role of the stress the size of the force.

green-laser1

If you can get green  laser stress, the change of elastic body wave and laser pens transmission speed, a scheme can get the stress the size of.Laser beams is dependent on the relationship between ultrasonic velocity on the stress state based on the measurement of the echo time is orthogonal polarization two wave, another scheme is referred to as sing around.Blue laser pointer by the Rayleigh wave and longitudinal wave in the surface of the component, evaluation caused by the strain displacement relationship of weakly nonlinear speed difference, thus determine the residual stress, namely using acoustoelastic effect method.

Green laser is the use of high energy laser pens excitation produces ultrasonic broadband surface is detected, and the use of optical methods for detection, high resolution, non-contact, long distance detection and many other advantages, especially suitable for harsh environment applications, such as in high temperature, corrosive, radioactive and was seized with fast laser beams moving speed under the environment of blue laser pointer.green-laser3

Green laser ultrasound particularly easy to achieve rapid automated scanning. This technique has both quantitative and qualitative laser pens detection of  accurately, and has the characteristics of non-contact, accurate and rapid nondestructive detection can achieve laser beams. Blue laser pointer has been applied to the field of attribute calibration, table surface and internal defect detection.green-laser4

The laser beam quality of kilowatt class fiber laser is continuously improved with the increasing of the power of the single core junction laser module.

Fiber green laser than its operating costs and power consumption is low, diode array excitation can be used is the laser pens. fiber  end pumped optical focusing system and use the corresponding pump source into the cladding of the fiber. After a period of development, high power laser diode array two can generate high power blue laser pointer, and good beam quality, the average running time can reach ten thousand hours. But the stringent requirements for laser beams, the stability factors and parameters of the pulse limit mode limits its wide application.

green-laser-2

Without complex optical focusing and green laser system. The single core can be produced with the same array of high output power, high quality laser pens and longer running time. Have a great relationship with the traditional mode of temperature blue laser pointer semiconductor, the need for accurate temperature control, and the fiber is not it. The model only has a relationship with the geometric characteristics of single-mode fiber. The fiber laser beams can maintain the same beam mode is used in the whole process.green-laser-1

Modulation of the optical fiber green laser is through the control switch of the pump source. It can be very high frequency modulation of the optical fiber laser pens, or a single pulse operation. Unlike traditional solid-state laser, fiber blue laser pointer because of its perfect fiber cross-sectional area, without preheating, can be very broad the environmental conditions for stable operation. Such as beam quality, power and so on. These laser beams can choose linear polarization output or random polarization mode, power output in 10% to 100%, the final spot size will not change because of changes in the environment and power.green-laser-3

Single mode green laser because of its excellent beam quality is greatly improved the process of traditional laser! In traditional laser kilowatt fiber laser pens compared with the same power, cutting speed and the welding penetration depth has been greatly improved. In addition, the traditional blue laser pointer at a wavelength of 1 microns due to huge power consumption, maintenance and operation the high cost of the common maximum power is only 5 kilowatts, and 3 kW fiber laser beams than its operating costs and power consumption are much lower!green-laser-4

 

With the successful development of the key materials of all solid state lasers, the green laser display technology is greatly promoted.

Green laser based on  technology, such as the technology of laser pens alloy and laser cladding technology, using blue laser pointer melt and mixed metal powder, laser beams as the coating to cover the surface of materials. However, the process also have some shortcomings. The process temperature is high, the phenomenon of shrinkage during solidification, and paint dilution factors must be considered, in order to avoid the deformation of the material, the residual stress exist high strength and unnecessary metal.green-laser-1

The material in a small portion of the molecule is always better than other molecules of high temperature. When they absorb green laser when they are stimulated into a higher energy state. In some materials at green laser to bring the molecules to the original level lower than them, vibration is more “cold” away. The blue laser pointer and molecular ratio of the absorbed light contains more energy, which is called laser beams.green-laser-2

In the manufacture of metal furniture, butt joints of green laser laser beams welding are generally used to assemble edge and sub assemblies profiles after laser pens cutting and bending joint. For this shape, to ensure the quality of blue laser pointer on the weld joint, positioning and adjustment is particularly critical. Therefore, between the plate edges the distance should be less than 0.15mm. blue fiber laser beams device is the use of rare earth ion upconversion luminescence mechanism.green-laser-3

But in most cases, in order to improve the absorption efficiency and conversion efficiency of green laser pumped, pens or Pr will often use laser ions and Yb ions Co doped, sensitized by Yb ion, using the principle of multi phonon absorption to obtain blue laser pointer effect on the most efficient conversion, Tm/Yb Co doped and Pr/Yb Co doped this two types of laser beams upconversion fiber has been reported.

According to the working mode, the green laser can be divided into the blue laser pointer and the continuous wave laser radar

Green laser is generated mainly from high energy photon stimulated by a frequency of excitation on the atom radiation, and then get two photon characteristics. Then recycling incentives as like as two peas high energy levels of atoms, photons get exponentially growing, so the beginning of photon difference weak was increasing concern a.Green laser is generated in the process of.Blue laser pointer with the ordinary light of light in frequency, phase (coherence), the direction is different from the.Blue laser pointer in all of the photons have the same frequency and phase (coherence), direction, in addition to the laser or coherent light.

green-laser1

Green laser; high brightness, good direction, good monochromaticity, good coherence four characteristics. The receiving system of direct detection laser radar receiver system to signal, according to this principle can be used by the blue laser pointer range, the travel time to calculate distance.

green-laser3

We choose the green laser device is mainly based on the principle of frequency, durability, reliability, many aspects of cost and applicability of the.Green laser asked  to meet the above various aspects has the blue laser pointer characteristics of coherence is not high, for direct and indirect detection methods, blue laser pointer is to choose direct type.green-laser2

For the direct detection method also has two kinds of detection methods. One is the pulse type, its principle is based on the narrow pulse to record green laser the time to reach the destination, by measuring the time, use the formula  to calculate the starting point to the end of the distance. Where C is the speed of light, F for the round-trip time, distance R. two is a continuous, blue laser pointer is based on the principle of phase difference.

Green laser welding of this new type of welding technology, which has the advantages of solid and easy to achieve automatic control and so on.

The green laser connection, there are many defects, for example, the curing depth is limited by the device geometry; limit; green laser less than the local irradiation. Both have not cured adhesive dispensing device, and set the blue laser pointer, which makes the whole system become more complex, most notably in the actual use of the heating device. Such factors will exist on the device at the combination position offset trace, with the reliability of green laser and improve the practicability, with the rapid development of computer technology and blue laser pointer in blue laser, promoted the development of pointer.

Green laser and blue laser pointer is the two most widely used laser, now two kinds of lasers to do a simple comparison of green laser (wavelength of 1.06 m is in the aspect of material processing with the most extensive laser source. However, a lot of plastic and used as some special polymer flexible circuit board base material (such as polyimide), not by green laser treatment or heat treatment of fine processing. Generally is through the blue laser pointer device on the junction surface is fixed, the first is the blue laser pointer to the device junction, then through ultraviolet light irradiation curing.

The traditional green laser, leading to device coupling power value of arrhythmia, decrease in accuracy, influence the quality of products and production cycle is long, efficiency is not high. While the use of green laser welding welding technology of this model, with its solid welding, little deformation and high precision, fast speed, easy to realize automatic control etc., so blue laser pointer has become one of the important means. Therefore, blue laser pointer precision welding department developed a high speed automatic coupling of laser welding system.

This is the set of green  laser technology, automation control technology. Through the sensor control technology and electric arc pendulum mechanism, to achieve blue laser pointer adapter and the contact surface fitting, namely automatic leveling device. Usually two control surface gap between 0.01 ~ 0.03mm.

The advantage of green laser cutting is that it is a kind of non contact material processing method, so it will not damage the surface of the plate.

As we all know, green laser galvanized steel, galvanized by surface to protect the blue laser pointer inside the  carbon steel, long-term use is not easy to rust. This kind of plate blue laser pointer plate although than ordinary carbon steel plate is slightly more expensive, but because of green laser without the need for anti rust coating after the procedure, so from the cost of the whole product, or cost-effective.
green-laser1

The green laser.Blue laser pointer has already It is quite common for cutting cutting processing is that it is not a means of contact materials, so it will not damage the surface of the plate, and the section without any burr, is a big cuts after the procedure of processing methods. However, green laser also will encounter a variety of actual cutting to overcome the problem. Here we will look at the daily processing generally difficult cutting galvanized steel used by  and blue laser pointer solutions.

green-laser3

Green laser this is the most traditional cutting method has the advantages of blue laser pointer gas of low cost, but also in the sheet metal processing with carbon steel mainly, without switching auxiliary gas frequently, so.Green laser factory management but the drawback is that after oxygen cutting, the cut surface surface will have a layer of oxide skin if, then this will be directly welded with oxide skin products, for a long time, blue laser pointer will be the natural oxide skin peeling. This is one reason to weld welding of galvanized steel plates.

green-laser2

Using green laser nitrogen for high speed machining, due to the blue laser pointer function with nitrogen is different from combustion with oxygen, but play a protective role, so the cutting section does not produce oxide. Many companies also took a fancy to this advantage, so green laser of galvanized steel plate cutting is often processed by nitrogen. But the nitrogen gas cutting the disadvantage is here: because blue laser pointer cutting section completely without protection, so the product is easy to rust.

Laser green silicon material completely changed the form of electrical equipment manufacturing

The silicon material has completely changed the form of electrical equipment manufacturing green laser. This semiconductor rich is easy to be processed into small components, such as transistors, and method which is used can be extended to level of manufacturing industry, which makes the green laser components can be integrated by tens of thousands of production in a single chip.. these electronic engineers want to further expand the functions of the integrated circuit, so that they can create, processing and detection of green laser.

green-laser1

The processing speed of these green laser optoelectronic devices can accelerate the speed of digital information, and can realize the laser micron scale, for example, can be used in barcode scanner. However, the problem is that the silicon material is not an effective light generator.

green-laser2

An important consideration in any green laser structure is light feedback, ability of capturing light within the structure, to further drive the production of light. In the traditional green laser, this is achieved by placing a mirror in any one side of the light generating area. On the contrary, the use of the geometric equipment a cylindrical. This will put some green laser generated by the  capture in equipment on the wall, and forcing it to spread in the cylinder. This is called the whispering gallery mode, because the same effect will occur in a circular room, such as the dome of the cathedral in the sound.

green-laser4

This device has a unique function, the echo wall pattern extends to the silicon and green laser. can provide optical amplification, and silicon passive guide green laser. “the next step, we hope these ideas applied to room temperature equipment.” at higher temperatures will need to design and manufacture the laser is adjusted.
