These tables have only the most typical host crystals; lots of Other individuals exist, which happen to be much less routinely used.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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（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。
Which geometry, dopant and doping concentration on the get medium are most useful depend on a number of aspects. The offered pump supply (variety of laser diode or lamp) along with the envisaged pumping arrangement are very important components, but the material itself also has some affect. By way of example, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of the transversely cooled rod, operated with reasonably smaller pump and laser beam diameter, is much more appropriate than e.

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 illustration, Q-switched lasers attain an increased population density from the upper laser stage and are for that reason more delicate to quenching results and Power transfer processes; hence, a lessen doping density is often appropriate for these products. For prime-electrical power lasers, reduced doping densities will often be utilized to limit the density of heat technology, Though thin-disk lasers operate ideal with remarkably doped crystals. Quite a few laser solutions do not reach the total overall performance potential mainly because this sort of particulars haven't been effectively labored out.
Laser modeling and simulation may be used to reliably figure out the the best possible crystal Proportions, doping density And perhaps values of supplemental parameters.
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。
All those surfaces which might be passed by 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。
In 2017, we made the globe’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with particularly extensive emission spectra drives the event of laser diode pumped ultrafast solid-condition lasers. With the rise in pulse energy, peak electricity, and repetition amount of strong-state lasers, more info laser crystals will produce toward larger sizes, greater crystal top quality, and controllable essential effectiveness.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also acts like a heat sink. Greater crystals are frequently utilized for side pumping e.g. with higher-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。
