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。
Which geometry, dopant and doping focus of the gain medium are most advantageous rely upon many aspects. The accessible pump resource (sort of laser diode or lamp) and the envisaged pumping arrangement are essential things, but the material itself also has some impact. By way of example, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of a transversely cooled rod, operated with somewhat small pump and laser beam diameter, is a lot more proper than e.
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。
Certainly, it is vitally attractive that a presented crystal high-quality is manufactured continually, Despite the fact that distinct laser styles might have a distinct sensitivity to substance parameters.
g. a skinny disk. As An additional illustration, Q-switched lasers attain a better population density from the higher laser level and therefore are hence much more sensitive to quenching consequences and Vitality transfer processes; thus, a lessen doping density is often appropriate for these gadgets. For high-electricity lasers, decrease doping densities will often be utilized to Restrict the density of warmth more info technology, While slim-disk lasers get the job done finest with really doped crystals. A lot of laser solutions will not reach the complete overall performance potential because these types of information have not been thoroughly 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。
It is clear that distinctive purposes lead to extremely various needs on laser obtain media. For that reason, a broad variety of different crystals are used, and earning the right choice is important for setting up lasers with the best possible general performance.
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 a lot more than thirty yrs of experience in distributing laser crystals. Choose GWU to take advantage of our extensive expertise and in-area expertise!
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in some strong mount which also acts as a warmth sink. Larger crystals are usually used for facet pumping e.g. with significant-electric power diode bars.
