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 not hard to perform: just discover the lock icon in front of the URL while in the address bar and drag that to your bookmark toolbar While using the mouse. Just in case you locate the bookmark entry too very long, you could proper-click on it to edit the text, e.g. utilizing "RP Enc" instead of "RP Photonics Encyclopedia".
GWU offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide selection of technical specs. Other than the very well-proven supplies, innovative crystals with superb properties like Yb:CALGO can open up new horizons for demanding laser applications. It doesn't matter no matter if person items for R & D purposes are essential or cost-productive numbers in little, medium or substantial batches with in-time delivery to the generation line are needed: GWU’s devoted provider helps you to locate the most effective Main parts in your software.
Not surprisingly, it's very appealing that a given crystal high-quality is developed constantly, While diverse laser styles may have a different sensitivity to substance parameters.
g. a thin disk. As One more example, Q-switched lasers achieve the next population density while in the upper laser degree and so are hence much more sensitive to quenching outcomes and Electrical power transfer procedures; therefore, a reduced doping density is commonly suitable for these equipment. For top-power lasers, reduce doping densities are frequently used to limit the density of heat generation, although slender-disk lasers do the job most effective with really doped crystals. Lots of laser products and solutions will not reach the complete overall performance prospective simply because such facts have not been effectively 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。
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 cause incredibly distinctive prerequisites on laser gain media. Because of this, a broad range of various crystals are made use of, and earning the ideal alternative is important for constructing lasers with the best possible general performance.

For many causes, composite crystals have become well-liked. These have a spatially different chemical composition and might be manufactured with Particular shapes.
With that concept, a single will not want an extra saturable absorber crystal, in order that a single could website make much more compact Q-switched laser setups with reduce inner parasitic losses. Nevertheless, unwanted side effects could also arise, including obtaining undesired valence states from the included ions or Vitality transfers.
