Green laser is known as the power equipment in the heart of the transformer oil is an important medium for normal operation of the transformer, an insulating and cooling effect is equivalent to the heart of blood. The detection of transformer equipment is normal, usually from transformer oil samples and standard oil on the use of the analysis of the different gas content to reach a conclusion.

Green laser would allow the energy to focus as much as possible in time and space, so it will not “slowly”, nor “thick”.

Here is a bit, can “see” the energy for the green laser weapon is a serious loss, but also exposed their own design, in any case, you may have to make it look more dark and better.In addition, in order to maximize the killing effect of laser weapon, will allow the energy to focus as much as possible in time and space, so it will not “slowly”, nor “thick”.

More likely is that if the eyesight is good, you can see a less bright line, and then quickly disappear, but this line is not you see green laser, but the laser through atmospheric ionization trails after left. When you see when the strike has been laser2

First, if green laser the use of weapons is not visible, then what optical phenomena can not see, suddenly the target is destroyed. If it is visible in the Tyndall effect under the condition of strong observation is a chance to see the laser laser3

If people are observation targets, since the speed of light is too fast is no chance to see the green  laser. The laser beam is generally considered a Gauss light, fundamental mode and higher-order mode points, is difficult to appear a line slowly coarsening situation. Along the direction of the incident laser, should be like the stone into the water, the water spread feeling.


If the astronauts landed on the moon, how far would I use green laser to shoot him on earth?

The main problem is directional and intensity resolution problems. First, you green laser to hard alignment of the pupil. The astronauts only pointed the human eye can collect the laser laser1

The second is the strength of human sensitivity to resolution of the problem. The single photon state. However, the premise is the absolute darkness, so in this case even if the contrast of a photon is infinity. Astronauts will see a lot of radiation of the earth in space, then only the green laser energy compared with the background radiation to the human eye under the condition of resolution can be found. A better solution is to use 10Hz to improve the identification of flicker frequency, high frequency. So thepersistence of vision will make you still can not be laser3

Different green laser have different divergence angle, the general research several mrad, laser pen is more divergent, not suitable. Can calculate the range of irradiation to the moon, the average end transparent rate multiplied by the atmosphere, the human eye can identify the minimum contrast can be back to the sun. The sun and are quite different, completely dark earth the surface of the moon and the food, the 100W red laser should be laser2

If in the near sea level, a green laser light can be hundreds of kilometers away to see, so the light can also be seen on the moon? After all, 1000 km thickness is far less than the surface of the atmosphere is the light shielding ability.

The green laser sensor is particularly suitable for the measurement of rapid displacement changes without the need for an external force on the measured object

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 laser2

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 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.

Green laser is a device capable of absorbing a specific frequency of a beam rather than releasing a beam of light

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.laser pens1

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.laser pens2

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.

laser pens3

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.
