When the teacher asked the question of laser principle, the teacher praised me to observe carefully, then tell me this is the green laser light speckle interference phenomenon, because of the special high coherence laser. Gauss beam just shows a cross-section of the laser light intensity on the part of Gauss branch, and the scattered Never mind spot.
The particle state was named “green laser light“. The intensity of speckle pattern is random, can be generated by laser in rough surface reflection or laser through inhomogeneous media. Because most of the surface is rough on the wavelength of light, due to the high coherence laser, when light reflected from the surface of the object. Each point on the object to the appropriate distance of observation point vibration is coherent.
Green laser light is due to photons of frequency, phase and amplitude are the same, each encounter can interfere. Due to surface roughness, a beam of photons in the laser will be rough surface reflection to run around, so it encounters the same phase of the photon, the meeting place will brighten, meet the photon anti phase the place is dark.
The “green laser light” I was not very strict, but the expression of “a small light” laser beam inside the light. In the process of communication, the initial phase (shaking position start) is the same, but the instantaneous phase (the current position of the vibration transmission (with) go forward the process of continuous) to 2 pi (a circle) and the cycle of change.
Scanning is to produce light polymerization and curing area of green laser light, forming part of a thin layer. The table down a thick layer of distance, so that the cured resin surface and then deposited on a new layer of liquid resin, the scanning process, the next layer is repeated until the entire prototype manufacturing. Since the light polymerization is based on the interaction of light and not based on the action of heat, so the lower power laser source only at work.
In addition, because there is no thermal diffusion, the chain reaction and can better control, to ensure that green laser light does not occur at the laser point, so the high processing precision, good surface quality, the utilization rate of raw materials is close to 100%, can make complicated shape, fine parts, high efficiency. For the larger size of the parts. It can be used to block forming and bonding method of production.
In the automobile body manufacturing application green laser light can produce precision casting mold with the required proportion, which cast a certain proportion of the body metal model, the metal model can be used in wind tunnel and collision test, thus completing the final evaluation of the body, to determine whether the design is reasonable.
For the green laser light test of intake pipe inlet pipe is composed of the inner shape of free surface is very complex, it is to improve the efficiency of charging, have very important influence on the combustion process. In the design process, need to do airway test of different air inlet pipe of the scheme, the traditional method is to use the method of manual processing by dozens of section describe the wood or plaster mold.

Using green laser light to make the tiger is must have the effect, because of the specific effects of tiger vary. Let the first thing you say as everyone knows things, animal belonging to the two color instead of a trichromat. In simple terms, the vast majority of animal are color blind. Two color viewer “means the person or animal can only distinguish red and green two colors, blue in; and trichromat can distinguish all the three colors.
Animal behavior science is a theory that says that two of the color of the animal may suddenly see the mobile green laser light is more sensitive, when they suddenly saw a moving object, fear center would be called amygdale brain impulse stimulation to make animal stress reaction, this is when people want to close to the animal should be slowly close.
Of course, this stress response is also different from the animals. Some animals may behave as panic, such as horses, and some animals show confrontation, as we see the cat and green laser light.
So the same way, when you take a green laser light to tease the tiger, as long as it is within the scope of the tiger’s rapid movement, the tiger will respond to stress
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.
