为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

Which geometry, dopant and doping focus on the get medium are most useful count on a number of components. The readily available pump resource (kind of laser diode or lamp) as well as the envisaged pumping arrangement are important variables, but the fabric alone also has some influence. One example is, titanium–sapphire lasers must be pumped with high intensities, for which the shape of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is much more ideal than e.

A superior surface top quality is certainly vital. Specs of surface area flatness tend to be much better than . This can help to prevent both equally scattering losses and wavefront distortions that may degrade the laser's beam good quality. Furthermore, scratch and dig technical specs
The maximum probable doping concentration can depend strongly to the host materials and its fabrication system.
Laser modeling and simulation can be utilized to reliably decide the optimum crystal Proportions, doping density and possibly values of extra 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。

There is certainly Laser Crystal an array of crystalline media, which can be grouped in accordance to big atomic constituents and crystalline buildings. Some essential teams 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。
