为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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：
GWU provides all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) with a wide range of specs. Besides the nicely-established products, modern crystals with fantastic properties like Yb:CALGO can open up new horizons for demanding laser purposes. It doesn't matter irrespective of whether particular person pieces for R & D functions are essential or Price-economical numbers in smaller, medium or massive batches with in-time shipping and delivery for the manufacturing line are wanted: GWU’s focused support helps you to locate the most effective Main parts for your personal application.
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。
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。
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。
Those surfaces that happen to be passed through the laser beam are Usually either 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 substantial transparency (very low absorption and scattering) in the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this more info depends on the quality of the fabric, determined by specifics with the fabrication process.
It may be oriented for in the vicinity of perpendicular incidence on the laser beam, or at Brewster's angle. It can be preset in some stable mount which also acts to be a heat sink. Larger sized crystals usually are utilized for aspect pumping e.g. with high-electrical power diode bars.
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。
