Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical elements) �?that happen to be utilized as get media for strong-state lasers. Most often, they are doped with either trivalent unusual earth ions or changeover metal ions.
Furthermore, some flexibility is missing in experiments if one simply cannot try out absorbers with various thickness or doping focus, such as, without exchanging the laser crystal itself.
Which geometry, dopant and doping concentration from the obtain medium are most advantageous depend on many components. The offered pump resource (variety of laser diode or lamp) as well as the envisaged pumping arrangement are crucial variables, but the fabric alone also has some impact. By way of example, titanium–sapphire lasers need to be pumped with large intensities, for which the form of a transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is 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 maximum probable doping focus can count strongly around the host product and its fabrication strategy.
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。

It may be oriented for around perpendicular incidence of your laser beam, or at Brewster's angle. It may be fastened in certain sound mount which also functions to be a warmth sink. Larger sized crystals are frequently useful for facet pumping e.g. with high-electrical power diode bars.
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。
