Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical supplies) �?that are utilized as gain media for sound-point out lasers. Usually, These are doped with both trivalent exceptional earth ions or transition steel ions.

Which geometry, dopant and doping concentration with the obtain medium are most advantageous depend on quite a few things. The out there pump source (sort of laser diode or lamp) along with the envisaged pumping arrangement are important factors, but the material itself also has some impact. By way of example, titanium–sapphire lasers ought to be pumped with large intensities, for which the form of the transversely cooled rod, operated with fairly smaller pump and laser beam diameter, is much more suitable than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

Of course, it is rather attractive that a presented crystal high-quality is developed persistently, Whilst unique laser types may have a different sensitivity to substance parameters.

The utmost achievable doping focus can rely strongly within the host material 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。

For quasi-3-degree laser get media or even a few-amount acquire media, a person typically has to limit the duration to a worth and that is way here too brief for effective pump absorption, as reabsorption results would or else spoil the functionality. For aspect pumping, extra considerations appear into play; Moreover productive pump absorption, it is crucial to get an appropriate spatial shape on the achieve profile.

The medium should have a substantial transparency (low absorption and scattering) while in the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the quality of the material, based on specifics with the fabrication course of action.

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。
