These tables have only the most typical host crystals; several Many others exist, which can be less frequently used.

These ions enable the crystal to amplify light-weight for the laser wavelength by means of stimulated emission, when Vitality is supplied to your crystal through absorption of pump light-weight (�?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 transition cross-sections of pump and laser transitions and likewise the upper-condition life time.

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。

Needless to say, it is rather attractive that a specified crystal excellent is developed persistently, Though various laser designs might have a distinct sensitivity to material parameters.

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

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。

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。

The medium must have a large transparency (reduced absorption and scattering) in the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this depends on the standard of the material, based on details with the fabrication procedure.

It may be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in certain stable mount which also acts as being a heat sink. Larger crystals are often used for facet pumping e.g. with superior-ability diode bars.

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
