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。
Laser crystals are optical crystals �?generally one crystals (monocrystalline optical components) �?that are used as acquire media for strong-state lasers. Generally, They can be doped with both trivalent rare earth ions or transition steel ions.
On top of that, some adaptability is missing in experiments if just one can't Check out absorbers with various thickness or doping focus, such as, devoid of exchanging the laser crystal by itself.
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：

A higher area quality is needless to say critical. Requirements of surface flatness are often much better than . This allows in order to avoid the two scattering losses and wavefront distortions that may degrade the laser's beam excellent. Moreover, scratch and dig requirements
The maximum possible doping focus can count strongly over the host material and its fabrication system.
The host crystal is a great deal more than simply a means to fix the laser-active ions at sure positions in Room. A variety of properties in the host product are very important:

For quasi-three-degree laser gain media or even a few-level gain media, a single often needs to limit the duration to a price that is as well limited for effective pump absorption, as reabsorption effects would in any other case spoil the effectiveness. For aspect pumping, added considerations come into play; Apart from productive pump absorption, it is crucial to acquire an appropriate spatial shape of the acquire profile.

In 2017, website we developed 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 extremely extensive emission spectra drives the event of laser diode pumped ultrafast good-state lasers. With the increase in pulse Vitality, peak electric power, and repetition price of reliable-point out lasers, laser crystals will establish towards bigger sizes, greater crystal good quality, and controllable essential effectiveness.
There may be a variety of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some important groups of crystals are:
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。
