These tables contain only the most typical host crystals; lots of Other individuals exist, which are considerably less routinely used.
These ions empower the crystal to amplify gentle within the laser wavelength by way of stimulated emission, when Electricity is equipped to the crystal by using absorption of pump mild (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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。
A higher surface area excellent is of course crucial. Technical specs of area flatness tend to be better than . This aids in order to avoid the two scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. On top of that, scratch and dig technical specs
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
The host crystal is far more than just a way to repair the laser-Lively ions at particular positions in Room. A variety of properties in the host content are very important:
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。
Those surfaces which are passed from the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium should have a large transparency (low absorption and scattering) in the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this is dependent upon more info the quality of the material, determined by information with the fabrication approach.
With That idea, a person would not need yet another saturable absorber crystal, to make sure that a person may well make far more compact Q-switched laser setups with reduced internal parasitic losses. However, undesired Unintended effects may take place, such as acquiring unwanted valence states with the involved ions or Electricity transfers.
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。
