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 in addition the higher-condition lifetime.
GWU offers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) having a broad number of specifications. Besides the well-founded resources, revolutionary crystals with remarkable properties like Yb:CALGO can open new horizons for demanding laser apps. Despite no matter whether individual items for R & D functions are demanded or Value-efficient figures in little, medium or substantial batches with in-time shipping and delivery to the manufacturing line are wanted: GWU’s dedicated provider really helps to find the ideal Main parts for your application.
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 most achievable doping focus can depend strongly on the host substance and its fabrication approach.
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。
It is obvious that unique purposes produce very various needs on laser obtain media. For that reason, a broad range of different crystals are employed, and generating the appropriate preference is essential for setting up lasers with ideal efficiency.

For numerous causes, composite crystals have gotten well known. These Have got a spatially various chemical composition and might be designed with Particular shapes.
It might be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It might be fastened in a few sound mount which also acts as being a warmth sink. Larger sized crystals tend to be employed for aspect pumping e.g. with read more higher-power 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。
