These tables contain only the most common host crystals; quite a few others exist, that happen to be less regularly utilised.

These ions help the crystal to amplify light-weight within the laser wavelength by means of stimulated emission, when Electricity is provided on the crystal through absorption of pump mild (�?optical pumping

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

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。

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：

GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a wide variety of specs. Apart from the effectively-proven components, progressive crystals with exceptional Qualities like Yb:CALGO can open new horizons for demanding laser purposes. It doesn't matter whether unique parts for R & D needs are expected or Charge-efficient numbers in smaller, medium or significant batches with in-time delivery for your creation line are required: GWU’s devoted support helps to discover the best Main elements for your personal software.

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 skinny disk. As Laser Crystal An additional illustration, Q-switched lasers arrive at a better populace density from the higher laser degree and so are for that reason much more delicate to quenching outcomes and Electricity transfer procedures; therefore, a lower doping density is frequently suitable for these equipment. For high-electric power lasers, decrease doping densities are sometimes accustomed to limit the density of heat era, Even though skinny-disk lasers function ideal with really doped crystals. A lot of laser products and solutions will not reach the comprehensive performance prospective simply because this sort of specifics haven't been appropriately labored 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。

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 various causes, composite crystals have gotten preferred. These have a spatially varying chemical composition and may be manufactured with Distinctive styles.

There exists a wide range of crystalline media, which can be grouped according to special atomic constituents and crystalline structures. Some significant teams 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。
