Optical component 1
The gain medium used for the carbon dioxide optical element is carbon dioxide mixed with helium and nitrogen, and can output far-infrared light centered at 9.6 ��m and 10.6 ��m. Carbon dioxide optics have high energy conversion rates, output powers ranging from a few watts to tens of thousands of watts, and the extremely high beam quality makes CO2 optics widely used in materials processing, scientific research, defense, and medicine.
Excimers are unstable molecules that are filled with a mixture of different rare gases and halogen gases in a resonant cavity and produced by lasers of different wavelengths. Excitation is commonly used by relativistic electron beams (energy greater than 200 keV) or lateral fast pulse discharges. When the unstable molecular bond of the excited excimer breaks and dissociates into a ground state atom, the energy of the excited state is released in the form of laser radiation. It is widely used in medical, optical communication, semiconductor display, remote sensing, laser weapons and other fields.
A chemical optical component is a special type of gas optical component, that is, an optical component that uses energy released by a chemical reaction to achieve population inversion. Most of these optical components operate in molecular transitions with typical wavelengths ranging from near-infrared to mid-infrared. The most important ones are hydrogen fluoride (HF) and cesium fluoride (DF). The former can output more than 15 lines between 2.6 and 3.3 microns; the latter has about 25 lines between 3.5 and 4.2 microns. Both devices currently have several megawatts of output. Due to its huge energy, it is generally used in nuclear engineering and military fields.
