The most common laser-Lively scarce earth ions and host media together with some common emission wavelengths are demonstrated in the next desk:

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 single crystals (monocrystalline optical elements) �?which can be made use of as get media for strong-condition lasers. Most often, They may be doped with both trivalent scarce earth ions or transition metallic ions.

In addition, some versatility is dropped in experiments if just one can't try out absorbers with distinct thickness or doping concentration, as an example, with no 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：

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 arrive at a greater population density while in the upper laser stage and are thus additional sensitive to quenching results and Power transfer processes; hence, a reduced doping density is commonly appropriate for these units. For prime-power lasers, lower doping densities tend to be used to limit the density of warmth generation, Though skinny-disk lasers do the job best with remarkably doped crystals. Numerous laser items will not reach the complete general performance prospective mainly because this kind of aspects have not been thoroughly worked out.

The host crystal is much more than just a way to repair the laser-Lively ions at particular positions in Room. Many properties with the host product are important:

People surfaces that happen to be passed because of the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

For numerous factors, composite crystals are becoming preferred. These Use a spatially various chemical composition and may be made with Distinctive designs.

It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in certain solid mount which also functions to be a heat sink. Greater crystals are frequently utilized for side pumping e.g. with higher-power diode bars.

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。
