Several types of lasers, such as carbon dioxide lasers that operate and emit infrared light, are used in a variety of military applications. The earth’s atmosphere is relatively more transparent to infrared rays. For this reason, this type of laser has proven to be effective for military ranging using methods such as LIDAR (Light Detection and Ranging). The laser beam provides information about the distance between the observer and the target location. Industrial applications of lasers (cutting and welding). The green laser pointer provides a high-power beam that can be effectively used in a variety of industrial applications, such as welding processes, etching processes, shot peening and drilling processes, composite preparation, and laser-based cutting for hard metal or glass cutting processes. Today, these instruments are also used for surface cleaning including the elimination of impurities and contaminants on the surface of materials. Carbon monoxide 2 is used for engraving on materials, and the equipment is also used for SLS selective manufacturing process or selective laser sintering.
An excimer laser or excimer laser is a laser that uses ultraviolet light to generate microelectronic devices, semiconductor integrated circuits, and micromachines. Nikolai Basov (Nikolai Basov) M. Popov and VA Danilychev invented the excimer laser at the Lebedev Sports Academy in Moscow in 1970. Excimer is an abbreviation for "excited dimer", and excimer is an abbreviation for "excited complex". It was originally Nikolai Basov (Nikolai Basov). M. Popov and VA Danilychev used a xenon dimer or Xe2 to excite it with an electron beam to generate stimulated emission with a wavelength of 172 nm. The laser wavelength of the ruby high powered laser is 694.3nm, and the photoelectric conversion rate is low, only 0.1%. But its long fluorescent lifetime is good for energy storage, and it can output higher pulse peak power. The laser produced by a ruby ​​rod with a pen core thickness and a finger length can easily penetrate the iron sheet. Before the more efficient YAG laser appeared, the ruby ​​laser was widely used in laser cutting and drilling. In addition, 694nm light is easily absorbed by melanin, so ruby ​​laser is also used for the treatment of pigmented lesions (skin spots).
