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。

Laser crystals are optical crystals �?usually one crystals (monocrystalline optical components) �?which are utilised as gain media for good-state lasers. Typically, They're doped with both trivalent exceptional earth ions or changeover metal ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

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。

g. a thin disk. As A further instance, Q-switched lasers arrive at a better inhabitants density within the upper laser amount and are as a result additional delicate to quenching effects and Vitality transfer processes; thus, a lessen doping density is often appropriate for these devices. For high-electrical power lasers, decrease doping densities will often be utilized to Restrict the density of warmth era, Even though thin-disk lasers function very best with extremely doped crystals. Numerous laser products do not get to the entire functionality probable due to the fact this sort of aspects haven't been appropriately labored out.

The host crystal is far more than just a method to repair the laser-Energetic ions at certain positions in Room. A variety of properties from the host content are very important:

People surfaces which can be handed because of the laser beam are Usually possibly oriented at Brewster's angle or have an anti-reflection coating.

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 globe’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally broad emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the rise in pulse Power, peak electricity, and repetition rate of sound-condition lasers, laser crystals will produce toward larger sized dimensions, higher crystal high quality, more info and controllable important efficiency.

There may be a variety of crystalline media, which can be grouped in accordance to special atomic constituents and crystalline buildings. Some significant groups of crystals 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。
