This kind ofgreen laser pointer applies a mini design
Atmospheric laser communication capacity, confidentiality, and immune to electromagnetic interference.
 And because the test vehicle is too far away, and is on the move, or the body is not flat, which led to the success of laser velocimetry low degree of difficulty, especially the work of police officers on duty strength of large, easily tired.
4, in view of the principle of laser velocimetry, laser speed device could not have used in the campaign, only in the stationary state of the application; For the second-level laser of green laser pointer, warning sign should be stuck to the body.Therefore, the 200mW Laser Pointer gun can not be called "mobile electronic police." When used in the stationary state, the driver is easy to find a test, and are not the intended purpose.
5, expensive, and now through the regular channels of the laser gun imports (excluding viewfinder and control part) the price at least one million dollars or so.
Beijing Optoelectronic Technology Co., Ltd. Leiser Department 010-64664911 main use of laser processing YAG, CO2 100mW laser pointer marking machine for professional laser marking, laser engraving business processing companies. Here are some control measures for the second-level laser of green laser pointer.YAG, CO2 laser marking machine adopts computer control, the use of high-tech laser technology, in a variety of laser engraved on metal and nonmetal, laser tag.
Laser marking method compared to traditional markers (such as ink jet, erosion, EDM, stamping, screen printing, etc.) has the following characteristics:
1 can tag any graphics, text, bar codes, two-dimensional code can be automatically numbered, printed serial number, batch number, date.
(2) laser tag, not because of environmental relationships (such as moisture, acid and alkaline) spontaneous regression, but a permanent hold, can not easily be fake, with good security features.
3 no "tool" wear and tear, non-toxic, pollution-free, high environmental protection.However, better avoid staring the first-level laser of 5mW laser pointer for a long time.
4 mark of good quality - a non-contact processing, the processing of materials does not produce mechanical stress, no damage to the items to be processed, accurate and beautiful.
5 can be ultra-fine micro-graphic mark.
6 beautiful graphics, fast processing, personalized design.
The main application areas: gold and silver jewelry, watches, glasses, clothing, cutlery, tobacco, beverages, gifts, mold, medical equipment, instrumentation equipment, sanitary ware, office supplies, household goods, hardware tools, lighting and sound, trademarks, signs, electronic components, automotive, and aerospace industries.The first-level laser of Blue Laser Pointer doesn’t need any control measures.
[Laser communications]
Laser communications, laser transmission in the atmosphere of a space communication. Laser atmospheric communication transmission equipment mainly by laser (light source), optical modulator, optical transmitter antenna (lens) and other components; mainly by the optical receiving device receiving antenna, optical detectors and other components.
Information is sent, the first converted into electrical signals, and then by the modulated light modulator to generate the laser beam on the laser, the optical antenna out. Here are the control measures of green laser pointer in different levels.Information received, the optical receiving antenna will receive the optical signal is focused, sent to restore the light detector into an electrical signal, in the reduction of information.
