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。

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

Moreover, some versatility is missing in experiments if one can't try out absorbers with distinct thickness or doping concentration, by way of example, 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：

Needless to say, it is extremely fascinating that a presented crystal high quality is made consistently, Whilst unique laser patterns can have a unique sensitivity to materials parameters.

g. a thin disk. As A different example, Q-switched lasers access a greater populace density within the upper laser degree and so are therefore much more sensitive to quenching outcomes and Electrical power transfer procedures; as a result, a decrease doping density is frequently appropriate for these units. For prime-electricity lasers, decrease doping densities will often be utilized to limit the density of warmth technology, Whilst slender-disk lasers get the job done finest with remarkably doped crystals. Quite a few laser solutions usually do not reach the full performance opportunity mainly because these details haven't been correctly labored out.

Laser modeling and simulation may be used to reliably establish the optimum crystal dimensions, doping density And maybe values of further parameters.

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 developed the entire world’s major Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with really wide emission spectra drives the development of laser diode pumped ultrafast sound-condition lasers. With the rise in pulse Electrical power, peak power, and repetition charge of reliable-condition lasers, laser crystals will acquire to larger dimensions, greater crystal top quality, and controllable essential effectiveness.

There is a wide range of crystalline media, read more which can be grouped according to important atomic constituents and crystalline buildings. Some vital teams of crystals are:
