Laser Pointer  can be used to burn black material or balloon.
Semiconductor lasers in laser ranging, laser radar, laser communications, laser simulation, weapons, laser warning, laser-guided tracking, igniting the detonator, automatic control, testing equipment, such as a wide range of applications, the formation of a broad market in 1978. the semiconductor lasers used in optical fiber communication systems, semiconductor lasers can be used as light sources and indicators of the optical fiber 7 communication and optoelectronics system LSI planar process. due to the excellent characteristics of semiconductor lasers with ultra-compact, high efficiency and high-speed work, so the development of such devices, and optical technologies closely integrated with optical communications, optical transform, optical interconnects, parallel lightwave systems. In addition, since the semiconductor laser can be achieved by changing magnetic fields or adjust the current wavelength tuning, and can get to the line width is very narrow laser output, so the use of semiconductor lasers resolution spectroscopy study of tunable lasers is an important tool for in-depth study of the structure of matter and the rapid development of laser spectroscopy.
Although the semiconductor laser power into the most effective device of the laser, but the power will inevitably produce large amounts of heat. This requires the bar to be fitted with a metal heat sink, with thermoelectric cooler or cold water cooling devices. effective cooling in the case of CW work has been the main design considerations of the multiple components. So far, the cooling method with thin copper heat sink in the bar between the septa, and then the component on a copper heat sink so the cooling water flow in the bar behind and around and through the main heat sink, this design method is the formation of "lC / W" thumb relations law, will be a bar output power to improve the IW, so that the temperature of the bar relative to the heat sink temperature increases 1 ℃. The manufacturer will change the design of back end of Laser Pointer .
There is a practical limit to the lowest temperature of the cooling water, so the output power is set a limit of early semiconductor lasers, the designers have faced life and power output of ask a compromise in 1998, the optical power engineering and technical personnel microchannel cooling technology breakthrough that hot nine-gradient barriers. thickness of 1 mm copper cooling plates separated by a single bar, the cooling water flow through the board, the space inside these hollow plate separated into many thin blades of the cooling flow channel separated by a distance of several hundred microns. metal surface area in contact with the cooling water reaches the maximum. When the customer wants to use Laser Pointer to burn the match or balloon.
