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。
Furthermore, some versatility is shed in experiments if 1 are not able to Check out absorbers with unique thickness or doping focus, for example, with out 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：

A large floor high-quality is obviously critical. Requirements of area flatness are often better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam good quality. Moreover, scratch and dig requirements
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。
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。

In 2017, we created the whole world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb more info 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 rate of strong-state lasers, laser crystals will build toward much larger dimensions, greater crystal top quality, and controllable essential effectiveness.
There's an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline constructions. Some essential groups of crystals are:
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。
