These tables comprise only the commonest host crystals; many Many others exist, which might be significantly less regularly made use of.

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 �?generally one crystals (monocrystalline optical supplies) �?that happen to be applied as gain media for sound-condition lasers. Normally, They may be doped with both trivalent unusual earth ions or changeover metallic 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。

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

Laser modeling and simulation can be used to reliably ascertain the ideal crystal dimensions, doping density And perhaps values of extra parameters.

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。

These surfaces which can be handed through the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The read more medium should have a superior transparency (reduced absorption and scattering) during the wavelength areas of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the standard of the material, based on particulars of your fabrication method.

With that concept, a single will not need to have an extra saturable absorber crystal, in order that 1 might make more compact Q-switched laser setups with lessen inside parasitic losses. Even so, unwanted Unwanted side effects may also come about, for example obtaining undesired valence states of the included ions or Power transfers.

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。
