The most common laser-Lively rare earth ions and host media along with some usual emission wavelengths are revealed in the next table:

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 �?normally one crystals (monocrystalline optical components) �?which are utilised as obtain media for good-state lasers. Usually, they are doped with either trivalent rare earth ions or transition 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：

晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。

g. a skinny disk. As An additional illustration, Q-switched lasers reach a higher populace density during the upper laser degree and so are hence a lot more sensitive to quenching outcomes and Electrical power transfer processes; consequently, a decrease doping density is read more frequently suitable for these products. For top-ability lasers, lower doping densities are frequently used to limit the density of warmth technology, Even though thin-disk lasers function very best with extremely doped crystals. Numerous laser goods do not get to the entire functionality prospective since such aspects have not been properly worked 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。

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Unique crystalline components are very diverse concerning their hardness as well as other Attributes, which decide with which solutions and how conveniently they can be Minimize and polished with top quality.

For several good reasons, composite crystals have gotten well-known. These have a spatially various chemical composition and can be built with Exclusive designs.

There is an array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some important 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。
