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：

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

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。

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

Laser modeling and simulation can be used to reliably establish the the best possible crystal dimensions, doping density And maybe values of added 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。

For quasi-3-level laser attain media or maybe three-amount achieve media, 1 generally should limit the duration to a value which happens to be way too short for productive pump absorption, as reabsorption effects would normally spoil the overall performance. For aspect pumping, supplemental factors appear into Participate in; Apart from successful pump absorption, it is important to acquire a suitable spatial shape in the get profile.

In 2017, we developed the earth’s biggest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser more info Facility. The event of Yb and Tm doped GdScO3 laser crystals with very huge emission spectra drives the event of laser diode pumped ultrafast strong-condition lasers. With the rise in pulse Electrical power, peak energy, and repetition fee of good-point out lasers, laser crystals will develop in direction of larger sizes, larger crystal good quality, and controllable critical general performance.

It might be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in some sound mount which also acts as being a heat sink. Bigger crystals are frequently useful for aspect pumping e.g. with higher-power diode bars.

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。
