The commonest laser-active rare earth ions and host media along with some normal emission wavelengths are shown in the next table:
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。
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。
Furthermore, some overall flexibility is shed in experiments if one can not try out absorbers with distinctive thickness or doping focus, one example is, with out exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the higher-state life time.

In 2017, we developed the whole world’s most significant Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally broad emission spectra drives the development of laser diode pumped ultrafast sound-point out lasers. With the rise in pulse Power, peak electrical power, and repetition price of sound-state lasers, laser crystals will acquire toward more substantial measurements, bigger crystal high-quality, and controllable key general performance.
