Which geometry, dopant and doping focus on the obtain medium are most beneficial depend upon quite a few variables. The readily available pump resource (style of laser diode or lamp) as well as envisaged pumping arrangement are very important variables, but the fabric by itself also has some influence. For example, titanium–sapphire lasers should be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with relatively modest pump and laser beam diameter, is a lot more appropriate than e.

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。

Several laser crystal elements happen to be demonstrated in which some saturable absorber material is incorporated for passive Q switching of a laser.

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。

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。

For numerous motives, composite crystals are getting to be popular. These have a spatially various chemical composition and might get more info be manufactured with Specific designs.

There's a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline constructions. 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。
