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。

Laser crystals are optical crystals �?ordinarily solitary crystals (monocrystalline optical materials) �?which might be applied as gain media for sound-state lasers. Generally, they are doped with either trivalent uncommon earth ions or transition metal ions.

On top of that, some versatility is dropped in experiments if a person are not able to Check out absorbers with diverse thickness or doping focus, such as, devoid of exchanging the laser crystal alone.

Which geometry, dopant and doping focus from the get medium are most useful rely on many elements. The available pump source (form of laser diode or lamp) plus the envisaged pumping arrangement are important aspects, but the material itself also has some influence. For example, titanium–sapphire lasers should be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with rather smaller pump and laser beam diameter, is more correct than e.

A significant area high quality is naturally crucial. Requirements of floor flatness will often be better than . This assists to prevent each scattering losses and wavefront distortions which may degrade the laser's beam top quality. Furthermore, 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。

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。

For quasi-3-stage laser achieve media or simply 3-amount achieve media, 1 normally has to Restrict the length to a price which is way too brief for successful pump absorption, as reabsorption effects would usually spoil the efficiency. For facet pumping, extra things to consider occur into Perform; Moreover efficient pump absorption, it is vital to get an appropriate spatial form with the attain profile.

Diverse crystalline materials are certainly various relating to their hardness along with other Attributes, which figure out with which procedures And the way very easily they may be Reduce and polished with high quality.

For several motives, composite crystals have become well-liked. These Have a very spatially various chemical composition and may be made with Unique shapes.

There's an array of crystalline media, which may be more info grouped in accordance to special atomic constituents and crystalline constructions. Some significant 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。
