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（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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-state life time.

A large area high quality is not surprisingly significant. Requirements of area flatness are frequently a lot better than . This can help to prevent both equally scattering losses and wavefront distortions which might degrade the laser's beam quality. Also, scratch and dig 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。
Laser modeling and simulation can be employed to reliably establish the the best possible crystal Proportions, doping density And maybe values of added parameters.
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。
Those people surfaces which might be passed by the laser beam are Commonly 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 ought to have a substantial transparency (reduced absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the quality of the website fabric, based on specifics of the fabrication approach.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It may be mounted in a few good mount which also acts like a warmth sink. Greater crystals tend to be useful for aspect pumping e.g. with substantial-electric power diode bars.
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。
