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。
This is straightforward to do: just discover the lock icon before the URL in the handle bar and drag that towards the bookmark toolbar Along with the mouse. In case you locate the bookmark entry also very long, you can proper-click on it to edit the textual content, e.g. applying "RP Enc" rather than "RP Photonics Encyclopedia".
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 One more case in point, Q-switched lasers achieve the next population density while in the higher laser level and therefore are hence far more delicate to quenching consequences and Power transfer processes; for that reason, a decreased doping density is commonly suitable for these devices. For high-energy lasers, reduced doping densities are sometimes accustomed to limit the density of heat generation, although thin-disk lasers work best with remarkably doped crystals. A lot of laser products never get to the whole efficiency likely because this sort of aspects haven't been correctly labored 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。
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。
It is obvious that unique purposes produce very different specifications on laser acquire media. Because of this, a broad range of various crystals are made use of, and earning the appropriate alternative read more is essential for constructing lasers with the best possible efficiency.

GWU-Lasertechnik has a lot more than thirty decades of knowledge in distributing laser crystals. Opt for GWU to take pleasure in our wide knowledge As well as in-industry working experience!
It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be set in some sound mount which also acts like a heat sink. Greater crystals are generally utilized for side pumping e.g. with higher-energy diode bars.
