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。

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。

Additionally, some adaptability is lost in experiments if just one can't try out absorbers with diverse thickness or doping focus, such as, without having exchanging the laser crystal 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 vitally attractive that a offered crystal excellent is manufactured regularly, While distinct laser designs may have a special sensitivity to materials parameters.

g. a skinny disk. As An additional illustration, Q-switched lasers achieve the next population density from the upper laser amount and they are as a result a lot more sensitive to quenching effects and Electrical power transfer procedures; hence, a lower doping density is often appropriate for these devices. For high-electric power lasers, decrease doping densities tend to be utilized to Restrict the density of heat technology, Despite the fact that slender-disk lasers work very best with very doped crystals. Quite a few laser products tend not to reach the comprehensive overall performance likely due to the fact this kind of aspects have not been properly labored out.

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

It is obvious that unique applications produce pretty different requirements on laser acquire media. Due to this, a wide selection of different crystals are utilised, and generating the correct choice is essential for developing lasers with optimum general performance.

In 2017, we made the whole world’s largest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the development of laser diode pumped ultrafast strong-state lasers. With the rise in pulse Electrical power, peak electrical power, and repetition level of reliable-point out lasers, laser crystals will produce to greater measurements, greater crystal high-quality, and controllable key overall performance.

It may be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be mounted in some stable mount which also acts like a warmth sink. Greater crystals tend to be useful for side pumping e.g. with large-electric power diode bars.
