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。

Furthermore, some adaptability is lost in experiments if one can't try out absorbers with distinct thickness or doping focus, by way of example, without having exchanging the laser crystal itself.

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。

g. a thin disk. As A further instance, Q-switched lasers access a greater populace density during the upper laser degree and so are hence much more sensitive to quenching outcomes and Electricity transfer processes; thus, a lessen doping density is commonly appropriate for these equipment. For top-power lasers, reduce doping densities are frequently accustomed to limit the density of warmth technology, Whilst slender-disk lasers get the job done finest with hugely doped crystals. A lot of laser merchandise tend not to reach the full overall performance possible simply because such get more info aspects have not been properly worked out.

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。

For quasi-three-amount laser achieve media or perhaps a few-degree obtain media, just one typically must Restrict the size to a worth which can be too limited for efficient pump absorption, as reabsorption results would if not spoil the efficiency. For facet pumping, additional issues occur into play; Apart from successful pump absorption, it is important to obtain a suitable spatial condition of the acquire 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 more than 30 a long time of knowledge in distributing laser crystals. Opt for GWU to take pleasure in our large knowledge As well as in-subject practical experience!

It may be oriented for near perpendicular incidence of the laser beam, or at Brewster's angle. It can be preset in certain stable mount which also acts like a heat sink. Larger crystals are usually useful for aspect pumping e.g. with high-energy diode bars.
