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 �?typically solitary crystals (monocrystalline optical resources) �?which are employed as achieve media for stable-point out lasers. In most cases, They may be doped with both trivalent unusual earth ions or transition metal ions.

Moreover, some versatility is dropped in experiments if one particular simply cannot Check out absorbers with unique thickness or doping concentration, as an example, without having exchanging the laser crystal 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：

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 skinny disk. As Yet another case in point, Q-switched lasers attain an increased population density inside the higher laser degree and so are therefore a lot more delicate to quenching outcomes and energy transfer processes; as a result, a lower doping density is often appropriate for these gadgets. For high-electricity lasers, decrease doping densities will often be utilized to Restrict the density of warmth era, While slim-disk lasers get the job done finest with remarkably doped crystals. Quite a few laser solutions will not reach the full performance opportunity for the reason that these information have not been adequately worked out.

The host crystal is a lot more than just a method to repair the laser-Energetic ions at sure positions in here Area. Quite a few Attributes on the host product are important:

Those people surfaces which happen to be handed because of the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.

The medium ought to have a large transparency (reduced absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by facts from the fabrication course of action.

With That idea, just one won't have to have yet another saturable absorber crystal, making sure that just one could make a lot more compact Q-switched laser setups with reduce internal parasitic losses. Having said that, undesired Uncomfortable side effects may additionally take place, such as acquiring unwanted valence states with the involved ions or Electrical power transfers.

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。
