The most common laser-Lively rare earth ions and host media together with some regular emission wavelengths are proven in the following desk:

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 �?commonly single crystals (monocrystalline optical resources) �?which are utilised as attain media for reliable-state lasers. Normally, They are really doped with either trivalent unusual earth ions or changeover metallic ions.

On top of that, some flexibility is dropped in experiments if just one cannot try out absorbers with various thickness or doping concentration, as an example, with no exchanging the laser crystal by itself.

Which geometry, dopant and doping focus with the gain medium are most advantageous depend on a number of aspects. The offered pump supply (sort of laser diode or lamp) along with the envisaged pumping arrangement are very important aspects, but the material alone also has some impact. One example is, titanium–sapphire lasers should be pumped with large intensities, for which the shape of the transversely cooled rod, operated with comparatively little pump and laser beam diameter, is a lot more proper than e.

A large area high quality is naturally important. Specifications of surface flatness are frequently a lot better than . This will help to stop both equally scattering losses and wavefront distortions that may degrade the laser's beam quality. In addition, scratch and dig specifications

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。

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

For quasi-3-amount laser achieve media or even three-amount gain media, a person usually really should limit the size to a worth which can be far too brief for productive pump absorption, as reabsorption consequences would or else spoil the effectiveness. For facet pumping, extra issues appear into Enjoy; besides productive pump absorption, it is important to acquire an acceptable spatial condition of the get profile.

Diverse crystalline supplies are very diverse concerning their hardness and also other properties, which establish with which methods And the way quickly they may be Lower and polished with high quality.

For many good reasons, composite crystals have become common. These Possess a spatially varying chemical composition and will be manufactured with Particular styles.

There is an array of crystalline media, which may be grouped according to big atomic constituents and crystalline buildings. Some important 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。
