Laser crystals are optical crystals �?commonly single crystals (monocrystalline optical elements) �?which happen to be applied as attain media for strong-point out lasers. Usually, They may be doped with both trivalent rare earth ions or transition metallic ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping concentration in the get medium are most useful rely on many components. The readily available pump resource (style of laser diode or lamp) and the envisaged pumping arrangement are very important factors, but the material itself also has some affect. For example, titanium–sapphire lasers should be pumped with high intensities, for which the form of a transversely cooled rod, operated with comparatively small pump and laser beam diameter, is much more ideal than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

The most achievable doping focus can count strongly on the host materials and its fabrication technique.

A couple of laser crystal materials are demonstrated where some saturable absorber substance is incorporated for passive Q switching of the laser.

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。

Unique here crystalline components are very unique concerning their hardness and various Homes, which determine with which approaches and how simply they can be Minimize and polished with good quality.

The medium must have a large transparency (reduced absorption and scattering) while in the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this relies on the standard of the fabric, based on facts with the fabrication course of action.

There may be a wide range of crystalline media, which can be grouped in accordance to special atomic constituents and crystalline constructions. Some important teams of crystals are:

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
