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。

Additionally, some versatility is dropped in experiments if a person cannot try out absorbers with various thickness or doping focus, such as, without exchanging the laser crystal itself.

Which geometry, dopant and doping concentration with the get medium are most useful rely upon many variables. The offered pump supply (kind of laser diode or lamp) and also the envisaged pumping arrangement are important components, but the material by itself also has some impact. Such as, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is more correct than e.

激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。

A superior surface top quality is certainly important. Specifications of floor flatness are sometimes much better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam top quality. Moreover, scratch and dig specs

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

In 2017, we developed the entire world’s major Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with very extensive emission spectra drives the event of laser diode pumped ultrafast good-point out lasers. With the rise in pulse Power, peak electrical power, and repetition amount of stable-point out lasers, laser crystals will establish towards larger sizes, higher crystal high quality, and controllable important efficiency.

There may be a wide range of crystalline media, which click here can be grouped in accordance to big atomic constituents and crystalline structures. Some critical 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。
