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:

激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成,激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时,则构成自激活激光晶体。

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。

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。

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。

For quasi-a few-degree laser gain media or even three-stage obtain media, a person often needs to Restrict the size to a value which is far too brief for effective pump absorption, as reabsorption consequences would otherwise spoil the general performance. For facet pumping, additional considerations come into Participate in; Moreover successful pump absorption, it is crucial to obtain a suitable spatial condition from the gain profile.

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。

GWU-Lasertechnik has in excess of 30 a long time of encounter in distributing laser crystals. Decide on GWU to gain from our broad awareness and in-field encounter!

With that concept, a person isn't going to need to have a further saturable absorber crystal, to ensure that one particular may make a lot more compact Q-switched laser setups with decrease inside parasitic losses. Even so, undesirable side effects may also come about, for instance acquiring undesirable valence states in more info the involved ions or energy transfers.

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。
