These tables incorporate only the most common host crystals; lots of Many others exist, which can be significantly less frequently utilised.
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。
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。
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：
GWU delivers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) using a broad number of specs. In addition to the effectively-established materials, progressive crystals with superb properties like Yb:CALGO can open up new horizons for demanding laser programs. Despite irrespective of whether particular person parts for R & D applications are demanded or cost-successful quantities in small, medium or significant batches with in-time shipping for that creation line are desired: GWU’s dedicated services helps you to find the most effective core parts to your application.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
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 utilized to reliably ascertain the the best possible crystal Proportions, doping density and possibly 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。

The medium should have a significant transparency (reduced absorption and scattering) from the wavelength locations of pump and laser radiation, and great optical homogeneity. To some click here extent, this will depend on the standard of the fabric, based on specifics with the fabrication process.
It might be oriented for around perpendicular incidence in the laser beam, or at Brewster's angle. It may be set in certain good mount which also functions like a heat sink. Larger crystals tend to be useful for side pumping e.g. with higher-power diode bars.
