Blue laser pointer is not the same as fixed people imagine, but every day for a change or MS cm level. Both the sun and the moon in the gravitational pull of earth, and continental drift, changes in ocean currents and ice age glaciers degradation change around quality caused by crustal rebound, inertial motion will change the earth, so as to change it is rotated.

Blue laser pointer using radio dish on the earth at a distance are observed in the distant universe, quasars from time to time flashing bright “Lighthouse”. When the parabolic antenna is widely distributed through the calculation will be recorded to a brightness change, geodesist can calculate the rotation rate of the earth’s axis and coordinate.

The focus of information a few kilowatts of continuous blue laser pointer

The focus of information a few kilowatts of continuous blue laser pointer, you can see the distribution of light beam in the focal region and intensity corresponding to a beam cross section distribution is very intuitive, can be seen in the center of the beam intensity is low, the intensity distribution of the ring, is probably the TEM01 mode, the light beam M2 is about 2.24. General quality, but high energy CO2 laser basically is just like laser pointer1

Blue laser pointer for relatively thin materials, the impact is not big, but for thick material, determine the effect of material relative to the focus position of processing is very important, the focus position is different, and the effect of energy materials received when processing is completely different.

Red is blue laser pointer, sampling a plane high speed rotating probe, and the sampling light to the detector through the internal optical path, to determine the sampling energy, and record the probe position and angle when Saowan the corresponding area, through the computer will correspond to the data synthesis and the light intensity distribution information corresponding to the cross section of the completion of a set of laser pointer3

Simultaneous measurement of mobile control and blue laser pointer. High precision positioning and fixing device is relatively easy, has reached nm or even nm level positioning, but repeated positioning device of high speed will be affected by various factors, the completion of a complete test requires thousands of synchronization of motor stability demand is very high, if stuck, the equipment basically scrapped.


Therefore, the main direction of the blue laser pointer has high average power, high peak power two routes

Blue laser pointer chemical energy, mature technology, the United States will be equipped with oxygen iodine laser target played on Boeing airplane, maintenance disadvantage is expensive, usually toxic chemical dyes, so the most fire is mainly solid laser weapons, such as slab type, disc type solid laser is to support structure of large power stability output.

Comprehensive high average power, high peak power, high beam quality blue laser pointer is promising, the most worth doing is disc end pumped solid-state laser. The disc, fiber, lath structure is to heat, heat production is always the biggest problem of high power laser pointer2

A parameter blue laser pointer must be considered is the photoelectric conversion efficiency. If the conversion efficiency is too low, the power consumption is too large, vehicle, airborne is not good, this is why the current to achieve the laser weapons targeting most land-based, shipboard, large aircraft equipped with energy, otherwise is a problem.

In addition, in order to output high beam quality, directly using the blue laser pointer output seems not much, but with the laser power, light – light – > > series, more conversion efficiency is lower, and in order to pumped, Ura Hikaruhikaruko energy is greater than the laser output of the photon energy, therefore may be used in nonlinear crystal the wavelength of the frequency doubling efficiency, as can be imagined.

Blue laser pointer diffuse reflection on the exposed skin will burn

Blue laser pointer energy is 8 * 250J, and a rifle bullet muzzle kinetic energy, but the power is so short duration of the order of TW. The laser can not continuous playing so strong, after a few hours. At that time, after the target used is a metal sheet a few millimeters square size, after completely unable to find it. According to the staff said, by the end of the chamber when cleaning might be under the metal slag layer is very thin.

Blue laser pointer to a moment. The video apart and found only one frame of the left side is bright, the previous frame and the next frame is black (that is CCD from left to right a refresh). You can see through the target room window, the scattered light is very strong (the presence of personnel not heard of any close your eyes and be as blind accident).

In general, like doing laboratory experiments of blue laser pointer in femtosecond nanosecond air will produce ionization. Like the shooting on the glass, can be observed in the traces of internal and external to the glass, but it did not seem to trace between the observed erosion. In fact, the laser light path through the target glass, but the adjustment method can make the laser at the target before (without destroying the glass, because the glass is transparent) and then arrive at the role of glass laser pointer3

Small power to cut thick glass, just as a demonstration purposes only. But the blue laser pointer power of this machine is so small that the laser injection is not easy to identify with the naked eye, there is a demonstration. A man with his hand in front of the laser spot waved. Then, a a gray hair is very obvious that the brothers are the center of the palm. On the back of his hand.

Beam quality is one of the important performance evaluation indexes of blue laser pointer, and has been a hot spot in the field of laser optics

The effect of spatial filter is to improve the quality of blue laser pointer, strictly speaking, each node needs to monitor the image transfer in near field and far field. In addition, the input and output wavefront spatial filter is a very important parameter to ensure the basic performance of the laser device, optical element diameter before is relatively small, mainly affected by the wavefront collimation.

As the optical element diameter increases, making alignment aberration introduced by frequency ripple wavefront error will affect the near field and far field distribution, so the monitoring beam quality needs to take into account the near field, far field and wave parameters to complete, such as can be detected at the same time the three parameter is the ideal location of.Blue laser pointer the direction of transmission through one optical element, optical element with wavefront error and wavefront diffraction effect change, near-field and far-field wavefront distortion by the same position, only the “eye”. The “Mami”.blue laser pointer2

Blue laser pointer detection with the development of SG series device, from the beginning of “Shenguang I measurement of laser parameters are complete, including the detection of laser beam parameters, near field, far field and wave.20 years ago the Shenguang II development process, further optimization of the near field and far field instrument is an important instrument the role of reasonable arrangement of the optical path and beam quality monitoring and control.

Data processing is introduced as the beam filling factor of near field distribution of evaluation parameters, describe blue laser pointer geometric volume and high ratio of beam peak for the rectangular volume. Near field instrument monitoring the Shenguang II optical image transfer in strict accordance with the arrangement, can greatly improve the beam quality.

Green laser aspheric optical parts have excellent imaging quality with spherical optical parts

Green laser application can be well corrected laser module in optical system, to improve the imaging quality of  laser pens blue laser pointer, to improve the ability to identify, range of action, it can take one or several small aspheric parts instead of more burning laser pointer, which simplifies the structure of instrument, reduce costs, and effectively reduce the the weight of the laser1

High power laser green laser light parts in modern high-energy, ICF ignition project, green laser and laser pens and deep space exploration strike system plays an extremely important role, increasingly wide range of applications. Some of these systems due to the use of environmental and related conditions, has very stringent requirements on laser laser2

Blue laser pointer traditional processing methods not only in time, efficiency and cost can not meet the requirements, it is more important to burning laser pointer can not be completed as many other materials and high power laser green laser light processing. At the same time, the traditional processing method can not solve complex aspheric surface parts, such as green laser ultra precision machining technology, the problem of conformal curved optical parts.

There is an urgent need to study to adapt to the rapid and efficient laser module, on the other hand, with the development of modern computer technology, laser pens, blue laser pointer, the development of various precision components manufacturing technology and environmental control technology, but also provides technical support for the implementation of the requirements of the burning laser pointer, which may become a reality.

Because the green laser system has the flexible processing mode, the high precision processing effect as well as the flexible controllable processing process

Long life laser module configuration green laser system has been basically close to the free maintenance, in the production process, laser pens grade 1, no other safety protection device.Blue laser pointer system is equipped with a suction device, will not cause the emissions of harmful substances. The control software with easy operation, the burning laser pointer is being replaced the traditional mechanical process, saving the cost of special laser1

High power laser circuit board  board and green laser light micro drilling and other fields, the green laser system exhibits a significant technological advantage. According to the thickness of the circuit board of different materials, laser module along the desired contour once or repeatedly cutting. Material is thin, cutting speed faster. If the cumulative laser pens is lower than that of penetrating materials required for blue laser pointer, only scratches on the surface of the material; therefore, can be two-dimensional code or code in the material marking, in order to follow the process of burning laser pointer.

The circuit board of the high power laser for frontback connection between the double plate line, or connection circuit for any layer between the conductive multilayer board. In order to need, after drilling the hole wall is plated with a metal layer. Now using the traditional green laser light has been unable to meet the drilling diameter smaller requirements: although improve the spindle speed, but the radial velocity of green laser can be reduced because the diameter is too small, even unable to complete the requirements of the laser module. in addition, considering the economic level, easy to wear laser pens supplies is a limiting laser3

In the early days, each layer of blue pointer laser circuit has been applied to the multi-layer circuit board.Burning laser pointer through the prepreg is pressed together; according to the circuit design, some regions of the high power laser need to be pressed and then cutting window.

Green laser is part of the electromagnetic spectrum, electromagnetic spectrum, including wireless, X and visible light

Green laser has some unique characteristics, so that they attract scientists laser module. on the one hand, most of them through the non conducting material, so they can be used for packaging box or by external security laser pens, because they are less than X ray energy, they will not damage human tissue or blue laser laser1

Burning laser pointer due to the chemical effect of different in different ways, is also used to analyze the different high power laser can be used to characterize the specific substances. This is called the green laser light green laser, this ability, the use of light materials analysis is one of the most promising and challenging laser laser2

In order to achieve this goal, laser pens scientists launched a series of  to the target object, then observe them and wave interaction after the blue laser pointer. burning laser pointer in eyes with visible light, we see a green type because of light reflection produced in the green high power laser laser3

The solution lies in the metal structure of new imaging green laser light. green laser and laser module when interacting with each other, they will produce a complex electromagnetic field, which is peculiar to the incident signal. Typically, these delicate areas are ignored, but researchers have realized that they can read out the pattern as laser pens, in order to determine the electromagnetic wave. The whole process can be through the micro chip blue laser pointer to complete, it can read burning laser pointer.

A new green laser flashlight, the mob was temporarily blind eye after irradiation, but do not leave sequelae

The green laser laser module flashlight by a science and technology enterprise development, laser pens is 3 cm in diameter, about 15 cm long and weighs about 180 grams. After the switch is turned on, the flashlight can launch spot small narrow beam blue laser pointer. both during the day or night, and in the mob near to about 30 meters, the high power laser can make the mob temporarily blind, to stop the mob shooting, driving escape arrest behavior.

The green laser light of the safe use of the minimum distance is 4 meters, not less than 4 meters with the green laser irradiation can make the eye of the mob, temporary loss of vision, but will not cause irreversible consequences. In addition, laser module will be conditioned to quickly closed, this reaction will also protect the eyes from laser pens continuous irradiation damage.

Except for the anti riot weapon, the blue laser pointer can be installed in the automatic rifle or pistol as a burning laser pointer. in the major military operations before the start of the offensive will usually turn off the radio network, only receives signals without signal, to avoid being found, this is called “high power laser“.

This green laser light can make in radio silence state secret service issued a simple contact signal with a flashlight, contact distance up to 10 km, green laser battery can work continuously for at least 500 hours.

Green laser system is relatively compact, power and auxiliary gas consumption rate is relatively low

Green laser we can absorb the inhaled gas in the air, odor and pollutants, including the potential risks of potentially carcinogenic chemicals. Indoor air through laser module filtration cycle, and return to the surrounding environment or be discharged to the outside.Laser pens certified the air filtration method, because of the excellent adsorption properties with activated carbon but as the preferred, and it has been widely laser1

As a comprehensive production factory, all parts of the blue laser pointer in the factory production of activated carbon air filter required (Figure 2). For burning laser pointer and the metal plate covering the carbon plate modules require a lot of linear cutting. The shell is in a turret punch press is made by using high power laser the material, Texas to plan to use green laser light to more efficient production of the shell.

“When green laser began to afford us the size of the enterprise, I started to pay attention to investigation and laser module, but the maintenance of equipment and their prices are relatively high, even the longest life expectancy of laser pens, also must be every 6 years to replace or renovate one, which means that the need to spend 40 thousand to 60 thousand U.S. dollars, blue laser pointer operating cost per unit time is higher. The cost is too high”green laser2

After extensive research, he finally chose the burning laser pointer. “when I finally settled in the high power laser eyes, I was shocked by its cost advantage,” he said to.Green laser light a good balance between performance and price, all the advantages of green  laser concentration fiber laser machine to the market the most competitive price.
