These tables incorporate only the commonest host crystals; several Many others exist, that happen to be less regularly applied.
These ions empower the crystal to amplify mild in the laser wavelength by using stimulated emission, when Electricity is supplied on the crystal through absorption of pump light (�?optical pumping
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical elements) �?which are employed as get media for strong-point out lasers. In most cases, They're doped with either trivalent exceptional earth ions or transition metallic ions.
Moreover, some versatility is missing in experiments if one cannot try out absorbers with various thickness or doping concentration, one example is, without having exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-point out life span.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Needless to say, it is rather appealing that a offered crystal quality is manufactured continuously, While diverse laser types can have a unique sensitivity to content parameters.
The maximum probable doping concentration can count strongly around the host product and its fabrication approach.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
Individuals surfaces which can be handed because of the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.

For numerous factors, composite crystals are becoming popular. These Have got a spatially various chemical composition and may be made with special shapes.
There is an array of crystalline media, which may be grouped according to important atomic read more constituents and crystalline constructions. Some critical groups of crystals are:
