Laser crystals are optical crystals �?usually one crystals (monocrystalline optical resources) �?which can be made use of as acquire media for reliable-point out lasers. Generally, These are doped with possibly trivalent exceptional earth ions or transition metal ions.
Furthermore, some overall flexibility is shed in experiments if 1 are not able to Check out absorbers with different thickness or doping concentration, as an example, without having 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：
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。
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。

In 2017, we created the entire world’s premier 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 really large emission spectra drives the event of laser diode pumped ultrafast reliable-condition lasers. With the increase in pulse Power, peak electrical power, and repetition charge of stable-condition lasers, laser crystals will build in the direction of greater measurements, better crystal high-quality, and controllable vital functionality.
There's an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some important teams of crystals here 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。
