After all, a few kilometers long-range projects a relatively small number. Europe benefits of infrared laser light products, mainly below 500 m, the real laser infrared technology to the civil engineering project which completed the extensive application of civil projects. Gradually in the field of monitoring night infrared laser light is widely used, but there are some problems in the course of the fundamental knowledge and understanding of the infrared laser lights and the use of some misunderstanding, so talk to from the following angles infrared laser light views, for the correct knowledge and understanding of the infrared laser light products. Therefore, the manufacturer should enhance the technology of producing, assembling and commissioning green laser pointer .
Laser red. Definition: laser, the original Chinese name is called “laser” and “les”, its English name called LASER meaning “light amplification by stimulated emission of radiation”, the English of the laser (Light Amplification by Stimulated Emission of Radiation) has been completely expressed the whole process of manufacturing the laser in 1964, a famous scientist Qian suggested that “light by stimulated emission was renamed the laser. Laser Special A directional: the laser light emitted born in one direction injection, the beam divergence angle is small, close to the ideal parallel light. The producer should renew the equipment and process of green laser pointer .
B monochromaticity: laser spectral width is very small, is the order of a few nanometers. So it has high brightness and good monochromatic light C, the energy density. 3, the semiconductor laser brief laser solid-state lasers (such as the ruby laser. Convert light to light, the wavelength is not the same), gas lasers (such as carbon dioxide lasers), the chemical laser (chemical energy into light energy), the semiconductor laser ( electrical energy into light energy). Laser infrared light is a semiconductor laser is the use of semiconductor materials, the electron energy levels in the hole and electron recombination process to reduce the release of a photon to produce light, then the photons in the cavity between the photon propagation direction of resonance specification laser. The quality of the parts and components of green laser pointer should be enhanced.
The size of the semiconductor laser is small, the order of magnitude of a few millimeters, the size of the laser, light emitting chips in one hundred microns; semiconductor laser electrical energy into light energy conversion efficiency of electro-optical conversion efficiency of at least 55%, LED lights the highest electro-optic conversion rate can reach 20 %. 4, the infrared laser light of infrared laser light output of semiconductor laser as the light-emitting device ① semiconductor lasers. Light, so it can be used as a lighting source. And because the laser have a good direction, expressed as the angle of the beam is small, the concentration of energy, spread to the far distance there is still enough light intensity, it is ideal for long-distance lighting. The most important feature of lighting is the infrared laser illuminator on distant targets. The customer can use green laser pointer with more safety and reliability.
The energy of the semiconductor laser in the vertical cross section of the beam energy distribution is uneven, and Gaussian distribution, the middle, gradually weakened to the edge, or was the light and dark stripe-like distribution. Therefore, the direct use of semiconductor lasers is not desirable as lighting effects (currently on the market of non-professional manufacturer of laser light, cottage version of the infrared laser light, a lot of problems, making the project the user on the infrared laser light, there are some negative impression). Europe benefits of laser technology companies through their own independent research and development of a unique optical system, the energy distribution of the vertical beam cross-section to achieve homogenization in order to achieve lighting applications. Infrared laser light + CCD camera night vision surveillance systems. Especially the green laser pointer market need and space are researched in the oversea market.
