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 easy to do: just locate the lock icon in front of the URL from the tackle bar and drag that to the bookmark toolbar While using the mouse. In case you discover the bookmark entry much too lengthy, you are able to correct-click it to edit the text, e.g. using "RP Enc" rather than "RP Photonics Encyclopedia".
GWU provides all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) using a broad number of specifications. Apart from the nicely-established materials, impressive crystals with excellent Attributes like Yb:CALGO can open new horizons for demanding laser apps. Irrespective of regardless of whether unique pieces for R & D applications are essential or Expense-successful quantities in smaller, medium or large batches with in-time shipping and delivery with the creation line are needed: GWU’s devoted company helps to discover the most effective core elements in your software.
A large floor high-quality is obviously critical. Specifications of surface area flatness are often better than . This aids to click here stop both of those scattering losses and wavefront distortions which may degrade the laser's beam top quality. Moreover, scratch and dig requirements
g. a skinny disk. As An additional illustration, Q-switched lasers attain the next inhabitants density in the upper laser amount and therefore are thus much more delicate to quenching consequences and Power transfer processes; for that reason, a lessen doping density is often appropriate for these devices. For high-energy lasers, reduced doping densities in many cases are used to limit the density of heat generation, although thin-disk lasers work best with highly doped crystals. A lot of laser merchandise usually do not reach the comprehensive general performance opportunity mainly because these kinds of particulars haven't been appropriately 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-a few-stage laser gain media or simply 3-level get media, a single often ought to limit the size to a worth that's way too short for productive pump absorption, as reabsorption results would in any other case spoil the functionality. For side pumping, added considerations arrive into Enjoy; Other than effective pump absorption, it can be crucial to obtain a suitable spatial form with the get 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。
For various motives, composite crystals are getting to be common. These Possess a spatially varying chemical composition and will be manufactured with Particular shapes.
Utilizing our promotion package deal, you could Show your brand, further under your products description, and these will been observed by quite a few photonics specialists.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
