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 focus on the get medium are most beneficial depend on several variables. The obtainable pump source (sort of laser diode or lamp) as well as the envisaged pumping arrangement are important factors, but the fabric alone also has some influence. As an example, titanium–sapphire lasers ought to be pumped with superior intensities, for which the shape of a transversely cooled rod, operated with somewhat little pump and laser beam diameter, is much more correct 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 doable doping focus can count strongly around the host substance and its fabrication technique.

Laser modeling and simulation can be utilized to reliably figure out the the best possible crystal dimensions, doping density and possibly Laser Crystal values of extra parameters.

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For quasi-three-stage laser achieve media or maybe 3-level attain media, just one usually must Restrict the length to a worth which can be also short for successful pump absorption, as reabsorption effects would if not spoil the functionality. For facet pumping, further criteria arrive into play; Moreover efficient pump absorption, it is necessary to acquire an acceptable spatial condition of the acquire profile.

The medium ought to have a significant transparency (lower absorption and scattering) within the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the quality of the fabric, determined by facts in the fabrication process.
