激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical products) �?that happen to be made use of as obtain media for solid-condition lasers. Most often, They may be doped with both trivalent scarce earth ions or transition metal ions.

Furthermore, some adaptability is lost in experiments if a single are unable to Check out absorbers with distinctive thickness or doping focus, for instance, devoid of exchanging the laser crystal by itself.

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the upper-condition life span.

Of course, it is extremely desirable that a offered crystal excellent is made constantly, Even though different laser models may have a different sensitivity to substance parameters.

The maximum doable doping concentration can rely strongly on the host substance and its fabrication technique.

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。

All those surfaces that happen to be passed via the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

Various crystalline products are quite various relating to their hardness as well as other Attributes, which decide with which solutions and how quickly they may be Reduce and polished with high quality.

The medium should have a higher transparency (small absorption and scattering) during the wavelength areas of pump and laser radiation, and great optical homogeneity. To get more info some extent, this depends on the caliber of the fabric, determined by facts in the fabrication system.

There's an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some vital teams of crystals are:

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
