激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
Which geometry, dopant and doping concentration in the acquire medium are most useful rely upon a number of factors. The readily available pump source (variety of laser diode or lamp) plus the envisaged pumping arrangement are essential components, but the material alone also has some influence. For example, titanium–sapphire lasers must be pumped with high intensities, for which the shape of the transversely cooled rod, operated with comparatively compact pump and laser beam diameter, is much more appropriate 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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The utmost possible doping concentration can count strongly within the host material and its fabrication technique.
Laser modeling and simulation can be utilized to reliably identify the ideal crystal Proportions, doping density and possibly values of extra parameters.
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。
It is apparent that various purposes result in pretty various needs on laser acquire media. Due to this, a broad assortment of various crystals are applied, and making the best alternative is check here important for setting up lasers with the best possible general performance.

The medium must have a higher transparency (reduced absorption and scattering) inside the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on details with the fabrication method.
There is a wide range of crystalline media, which can be grouped according to special atomic constituents and crystalline constructions. Some critical teams of crystals are:
