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 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.
When laser pens twisted, the hollow channel effect of the helical array in the light, similar to that described by general relativity, when light travels through the stars will occur due to gravitational bending in space.
The optical fiber as an internal laser pens. like pipeline light by wall, usually with a light guide fiber core, the refractive index of glass fiber rate higher than the refractive glass outer layer closed. The refractive index difference will cause the light reflection in the cladding interface, and trapped in tube shaped fiber in the core. The team LED for the first time the light guide without core photonic crystal fiber.
A typical laser pens consists of a piece of glass, a regular periodic array of holes in the glass and air volume. Due to the different refractive index and refractive index with periodic structure. This is the material called crystal, their atoms form a three-dimensional lattice ordered in the crystal salt or for example. In the conventional silicon crystal, such as insulator, conductor and semiconductor, the precise design of 3D structure determines the behavior of electrons.
The three-dimensional structure depends on the optical properties of a laser pens to periodically, in some butterfly wings, this structure determines the butterflies sparkling color. The optical properties to control material is very useful in a wide variety of applications. Developed by Philip Russell and his team of Marx Planck in Erlangen the visible spectra of the photonic crystal fiber can be used to filter specific wavelength or produce super white light.
Brenda created a wavelength of 1550 nm wavelength infrared signal – this is the common optical fiber cable with laser module. Then, he had a “WDM processing” of this signal, this signal can be converged to the same different wavelength of laser beam. After that, he through the lens of low cost on the laser transmission.
In addition, they also play life with the same equipment transmission of television signals. They will be 1 thousand MHz CATV signal input multiplexer; thus, television signals and other data from the same laser module. at the other end, they put a LED TV to watch the received TV channel.
Li Xiage believes that laser module can make data center managers more easily re arrangement of server frame. In this case, all servers need cooling can be placed in the same area, rather than scattered. At present, many large Internet Co are the data center energy consumption costs, one of the most important criteria as room location. For example, Google will be “cheap power” primary condition of the location of a data center.
Of course, it is difficult to evaluate this set of laser module in the end how much energy was saved, and the installation of the laser have enough price is also unknown. Professor Maria spent about $twenty thousand to build a prototype system, but he expects, if big companies are willing to invest, or integrated electronics continue to make a breakthrough, this set of system equipment costs will fall sharply and quickly.
The principle of green laser measurement based on simple geometric relations. The laser beam emitted from the laser diode is irradiated to the measured object surface. The reflected light through a lens, onto a photosensitive element matrix, the photosensitive element can be CCD/CMOS or PSD components. Strength of reflected light on the surface characteristics of the measured object.
The green laser probe to the measured object distance can be accurately obtained by calculation. The triangle rule using this method can obtain micron resolution. According to the different models, the measured data from external or internal controller through a variety of interfaces for evaluation.
Green laser is projected to be measured to form a visible spot on the object, through the spot can probe installation debugging is very simple, so the laser sensor is applied to many fields, become a popular choice for precise distance measurement. According to the different design, the optical measurement principle of maximum allowable measurement distance to 1m. according to the need of measuring tasks you can choose the range, very small, but has high measurement accuracy.
In addition a highly reflective mirror, or analyte, may cause the vertical light return without the formation of diffuse reflection, will also cause the measurement ineffective. So the use of green laser, we must first fully communicate with the manufacturers, not human can be measured results most probably it did not actually happen, but not good. The current international mainstream laser displacement sensor the brand, such as Germany and Japan, Kean m Iridium, will require customers in the selection of laser displacement sensor, notice the measured surface structure and reflective properties.
Green laser application can be well corrected laser module in optical system, to improve the imaging quality of laserpensblue 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 instrument.
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 module.
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 lasergreen 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.
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 tools.
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 factor.
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 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 pointer.
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 lightgreen laser, this ability, the use of light materials analysis is one of the most promising and challenging laser module.
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 chlorophyll.
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.
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 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 applied.
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”
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.
Green laser is located in the material cavity, when the working substance of a level between population inversion occurs when the distribution frequency in the level of spontaneous emission spectrum line width in laser pens, will gain and expand; because there are all kinds of cavity loss, blue laser pointer, in which the transmission can continue to decay. Oscillation, depends on the gain and loss of the burning laser pointer.
Green laser to get the light to make the light in the self oscillating cavity round trip by gain, at least in the propagation of.Laser pens loss compensation is generally used in semiconductor material such as “gain medium” produce a focused beam, which is a blue laser pointer is a coherent beam vibration direction, the vibration frequency of the same, the same phase or the phase difference of two beams remain constant, burning laser pointer interference phenomenon in the region will be met.
The opposite of green laser, is a kind of anti laser beam equipment can absorb specific frequencies rather than release beam. The incident beam into laser pens can interfere with each other, finally will offset each other. In this process, the blue laser pointer can be converted into heat energy released. And this process generally requires loss media participation with the laser gain medium loss medium such as silicon can make this.Burning laser pointer loss media is relative.
Some people may think that green laser plays a big role in the military. That we can use laser pens to resist blue laser pointer attack? The answer is not. We talked about in front of the burning laser pointer after the absorption of coherent light into heat energy, and the heat is very large.
