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。

Also, some adaptability is misplaced in experiments if one particular simply cannot Check out absorbers with different thickness or doping concentration, as an example, with out exchanging the laser crystal by itself.

Which geometry, dopant and doping focus on the get medium are most beneficial depend upon many variables. The offered pump supply (kind of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the fabric itself also has some impact. For instance, titanium–sapphire lasers must be pumped with superior intensities, for which the shape of a transversely cooled rod, operated with somewhat little 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。

Needless to say, it is extremely desirable that a provided crystal high quality is created persistently, Whilst distinctive laser types can have another sensitivity to substance parameters.

The most attainable doping focus can rely strongly over the host content and its fabrication method.

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。

Unique crystalline components are very diverse about their hardness and also other properties, which decide with which solutions and how simply they may be cut and polished with good quality.

In 2017, we produced the whole world’s biggest 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 extremely vast emission spectra drives the event of laser diode pumped ultrafast stable-point out lasers. With the rise in pulse energy, peak electrical power, and repetition fee of stable-point out lasers, laser crystals will produce to larger sizes, higher crystal high quality, and controllable important efficiency.

There may click here be a variety of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some crucial 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。
