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。

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：

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。

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。

g. a skinny disk. As another instance, Q-switched lasers achieve an increased inhabitants density during the higher laser amount and are therefore much more sensitive to quenching effects and energy transfer procedures; hence, a lessen doping density is commonly suitable for these products. For prime-electricity lasers, decrease doping densities in many cases are accustomed to limit the density of heat generation, Whilst slender-disk lasers get the job done finest with hugely doped crystals. A lot of laser items usually do not get to the complete overall performance prospective for the reason that these here kinds of information have not been thoroughly labored out.

A number of laser crystal supplies have been shown where some saturable absorber substance is integrated for passive Q switching of the laser.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Individuals surfaces which can be handed because of the laser beam are Ordinarily 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。

For several reasons, composite crystals have become common. These Use a spatially different chemical composition and can be produced with Particular designs.

It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be fastened in certain good mount which also functions as a heat sink. Greater crystals are frequently employed for aspect pumping e.g. with significant-ability diode bars.
