The commonest laser-Energetic scarce earth ions and host media along with some typical 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 �?ordinarily single crystals (monocrystalline optical products) �?that happen to be utilized as achieve media for solid-condition lasers. Typically, They're doped with both trivalent scarce 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 thin disk. As One more example, Q-switched lasers achieve the next population density while in the higher laser level and therefore are thus more sensitive to quenching outcomes and Electricity transfer procedures; hence, a reduce doping density is usually appropriate for these gadgets. For high-ability lasers, lower doping densities tend to website be used to limit the density of heat technology, although slender-disk lasers work very best with extremely doped crystals. Many laser products never get to the whole effectiveness likely since this kind of aspects have not been properly worked out.

The host crystal is much more than just a means to fix the laser-Energetic ions at selected positions in space. Numerous Homes with the host product are important:

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。

It is clear that different purposes produce very different specifications on laser acquire media. Because of this, a broad variety of different crystals are utilised, and generating the best selection is essential for developing lasers with ideal overall performance.

For many causes, composite crystals are becoming popular. These have a spatially different chemical composition and might be created with special designs.

You can find a wide range of crystalline media, which can 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。
