These tables consist of only the most common host crystals; a lot of Many others exist, which might be much less usually applied.
These ions allow the crystal to amplify light for the laser wavelength through stimulated emission, when Power is provided towards the crystal by using absorption of pump mild (�?optical pumping
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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the upper-point out lifetime.
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。
A superior area quality is obviously crucial. Requirements of floor flatness are sometimes a lot better than . This will help in order to avoid equally scattering losses and wavefront distortions which could degrade the laser's beam top quality. Additionally, scratch and dig specifications
The maximum attainable doping focus can count strongly within the host substance and its fabrication method.
A handful of laser crystal components have been demonstrated wherever some saturable absorber material is integrated for passive Q switching of the laser.
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium ought to have a significant transparency (minimal absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the caliber of the material, determined by aspects in the fabrication process.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in certain good mount which also functions for a warmth sink. More substantial crystals usually are utilized for side pumping e.g. with high-power diode bars.
