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 a snap to do: just find the lock icon in front of the URL from the address bar and drag that towards the bookmark toolbar Together with the mouse. Just in case you find the bookmark entry as well long, you are able to proper-click it to edit the text, e.g. using "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 skinny disk. As One more example, Q-switched lasers arrive at a greater populace density in the upper laser level and therefore are thus extra delicate to quenching outcomes and Power transfer processes; consequently, a reduced check here doping density is often suitable for these units. For high-energy lasers, reduced doping densities are often utilized to Restrict the density of heat technology, Despite the fact that slim-disk lasers get the job done ideal with hugely doped crystals. Several laser items usually do not reach the comprehensive general performance probable due to the fact this sort of details haven't been properly 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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

GWU-Lasertechnik has greater than 30 several years of practical experience in distributing laser crystals. Opt for GWU to take pleasure in our vast information and in-industry encounter!
With That idea, just one won't will need a further saturable absorber crystal, to ensure a person may perhaps make additional compact Q-switched laser setups with decreased inner parasitic losses. Nonetheless, unwanted Unwanted side effects could also arise, like getting unwanted valence states with the involved ions or Electricity transfers.
