Which geometry, dopant and doping concentration of the gain medium are most useful rely upon many variables. The obtainable pump source (variety of laser diode or lamp) plus the envisaged pumping arrangement are essential elements, but the fabric alone also has some influence. By way of example, titanium–sapphire lasers should be pumped with high intensities, for which the form of a transversely cooled rod, operated with somewhat tiny pump and laser beam diameter, is a lot more acceptable 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。

A significant surface top quality is needless to say vital. Specs of area flatness in many cases are much better than . This assists to stay away from both of those scattering losses and wavefront distortions which could degrade the laser's beam good quality. Furthermore, scratch and dig specifications

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 may be used to reliably figure out the the best possible crystal dimensions, doping density And maybe values of additional parameters.

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。

For quasi-3-amount laser acquire media as well as 3-level acquire media, one particular usually really should limit the size to a value which is much too shorter for productive pump absorption, as reabsorption consequences would in any other case spoil the efficiency. For facet pumping, extra issues appear into play; Apart from effective pump absorption, it can be crucial to obtain a suitable spatial shape in the achieve profile.

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。

There's a wide array of crystalline media, that may 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。
