200mW Laser Pointer of super high quality. In view of the principle of laser velocimetry, laser beam must be aimed at the vertical plane with the laser beam reflection point, and because the test vehicle is too far away, and is on the move, or the body is not flat, which led to low success rate of laser velocimetry , is difficult, especially the work of police officers on duty strength of large, easily tired. 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; Therefore, the laser 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. 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. 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. This kind of green laser pointer  is super bright.

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. 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. Atmospheric laser communication capacity, confidentiality, and immune to electromagnetic interference. However, when laser transmission in the atmosphere by rain, fog, snow, frost and other effects of attenuation should be increased, it is generally used for the border, island, across rivers and other short-range communication, and the atmosphere outside the inter-satellite communications and deep space communications . Early laser light source used in the majority of air traffic for the carbon dioxide laser, helium - neon lasers. Carbon dioxide laser output laser wavelength of 10.6 microns, the wavelength channel just in the atmosphere of low-loss transmission window is an ideal source of communication. From the late 1970s to the mid-1980s, due to the technology difficult to solve the all-weather, high mobility, flexibility, stability and other issues, atmospheric laser communications research at a low ebb. In 1988, Brazil announced the successful development of a portable laser atmospheric communication system. This line of military Unicom by infrared laser communications devices, its appearance as a pair of binoculars, laser diode installed in the above and a microphone. When used, the other party will aim to achieve binoculars communication, communication distance of 1 km, if the optical antenna fixed, the communication distance of up to 15 km. 100mW laser pointer  adopts the white-aluminum shell of high heat dissipation performance.

In 1989, the United States successfully developed a short distance, concealed atmospheric laser communication systems. In 1990, the United States tested for special warfare and low intensity warfare and ultraviolet wave communication, this communication system is fully in line with the tactical tasks, communication distance of 2-5 km; if appropriate beam processing, communication distance of 5 to 10 km. The early 1990s, Russia developed a high-power semiconductor lasers and laser atmospheric communication system began the practical study of technology. Soon launched within 10 km of semiconductor laser communication systems and the atmosphere in Moscow, Vallotton Nieshen, Tula and other cities application. In Wanie Shi River 4 km apart between the two power stations, set up from a semiconductor laser atmospheric communication system, the system can simultaneously transmit eight digital telephone. At a distance of about 200 km Vallotton Nieshi City and not far away from Moscow, has opened a semiconductor laser atmospheric communication system line. With the maturing of semiconductor lasers, optical antenna technology continues to improve production, signal compression technologies such as the rational use of laser atmospheric communication is re-vigor. Laser intensity and the ratio between the sun is one million, and it is a human creation. Color of the laser depends on the laser wavelength, the wavelength depends on the laser active material issue, he incurs the laser stimulation can produce the kind of material. Stimulation can produce deep pink ruby laser beam, it is used in medical applications, such as for skin treatment and surgery. The effective power of Blue Laser Pointer is high.

Recognized as one of the most expensive gas to produce blue-green argon laser beam, it has many uses, such as laser printing, in the microscopic eye surgery is also indispensable. Semiconductor laser-generated infrared light can be issued, so our eyes can not see, but its energy just to "read" CD, and can be used for optical fiber communications. Laser separation technology mainly refers to the laser cutting and laser drilling technology. Separation technology is the laser energy into the tiny space, focus, get 105 ~ 1015W/cm2 high radiation power density, the energy use of this high-density non-contact, high-speed, high-precision processing methods. In such a high optical power density irradiation, almost any material, laser cutting and drilling. Laser cutting technology is to get rid of the traditional mechanical cutting, heat treatment, cutting like a new cutting method, higher cutting accuracy, lower roughness, more flexible methods of cutting and higher productivity and so on. Laser drilling method as holes in solid materials processing methods, has become an application-specific processing technology has mainly used in aviation, aerospace and microelectronics industries. green laser pointerhas the good heat dissipation performance.

To the principle of laser mole is that the laser in an instant burst of color organizations put tremendous energy, and break the pigment decomposition, it can be swallowed by macrophages out, and then be excreted with the lymphatic circulatory system, thus achieve the purpose of the pigment to remove. Laser mole can be applied to many types of moles, such as including the three mentioned above nevi, nevus, port wine stains, etc., effects are obvious, and not easy to scars, the risk is small. Also go with a carbon dioxide laser mole. The suitability of laser technology. Prompt conditions were not suitable for laser treatment: the first. Ocular inflammation and disease activity; second. Purulent eye lesions; third. Has been diagnosed with keratoconus; fourth severe dry eye, accompanied by systemic Sjogren's syndrome; fifth central corneal thickness less than 450μm; sixth severe ocular adnexal lesions: eyelid defect, deformation, chronic dacryocystitis, etc.; seventh, systemic connective tissue disease and severe autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, multiple [1] sclerosis. 5mW laser pointer has the testing report of national authority.
