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 complete: just locate the lock icon in front of the URL from the address bar and drag that to your bookmark toolbar With all the mouse. Just in case you find the bookmark entry way too long, it is possible to ideal-simply click it to edit the textual content, e.g. using "RP Enc" as an alternative to "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。
A substantial area high quality is naturally vital. Specifications of surface area flatness will often be better than . This aids to stop both of those scattering losses and wavefront distortions which might degrade the laser's beam excellent. On here top of that, scratch and dig specifications
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation may be used to reliably decide the the best possible crystal dimensions, doping density And maybe values of extra parameters.
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 distinctive applications bring about quite unique requirements on laser acquire media. For that reason, a broad variety of different crystals are used, and earning the right preference is important for constructing lasers with optimum general performance.

The medium ought to have a significant transparency (very low absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the caliber of the material, determined by details with the fabrication approach.
Working with our promoting bundle, you can Exhibit your logo, more down below your solution description, and these will been viewed by many photonics gurus.
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。
