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。

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
GWU presents all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide a number of requirements. Other than the nicely-established components, revolutionary crystals with exceptional properties like Yb:CALGO can open up new horizons for demanding laser apps. It does not matter whether specific parts for R & D applications are demanded or Price tag-productive figures in modest, medium or massive batches with in-time shipping and delivery for the manufacturing line are necessary: GWU’s dedicated assistance helps to discover the best core factors on your software.
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
The host crystal is considerably more than simply a method to fix the laser-Lively ions at particular positions in Place. A variety of properties with the host material are crucial:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
Those people surfaces which happen to be handed because of the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.
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 must have here a substantial transparency (very low absorption and scattering) during the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this will depend on the caliber of the material, based on details of your fabrication system.
With that concept, just one won't will need an extra saturable absorber crystal, so that one particular could make a lot more compact Q-switched laser setups with reduced internal parasitic losses. Nevertheless, unwelcome Unwanted side effects might also occur, such as getting undesired valence states in the concerned ions or Power transfers.
