In this article you'll be able to post issues and comments. As far as they get acknowledged with the creator, they will appear previously mentioned this paragraph together with the writer’s remedy. The creator will determine acceptance dependant on certain conditions. Essentially, The difficulty needs to be of adequately broad interest.
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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the higher-point out lifetime.
GWU provides all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a wide variety of specifications. In addition to the perfectly-founded materials, modern crystals with remarkable Houses like Yb:CALGO can open new horizons for demanding laser applications. Regardless of no matter whether personal parts for R & D reasons are needed or cost-successful numbers in small, medium or substantial batches with in-time shipping and delivery with the creation line are necessary: GWU’s dedicated assistance helps to discover the very best Main factors to your software.
A high surface area quality is naturally vital. Specifications of surface area flatness in many cases are much better than . This allows in order to avoid both equally scattering losses and wavefront distortions which can degrade the laser's beam high quality. Furthermore, scratch and dig requirements
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 can be used to reliably determine the ideal crystal dimensions, doping density And maybe values of further parameters.
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-3-level laser attain media as well as three-stage obtain media, a single often really should limit the duration to a price that is far too quick for efficient pump absorption, as reabsorption consequences would if not spoil the functionality. For facet pumping, further criteria come into Engage check here in; Moreover efficient pump absorption, it is crucial to obtain a suitable spatial shape in the achieve profile.
Unique crystalline supplies are quite various about their hardness and also other properties, which ascertain with which techniques And just how effortlessly they are often cut and polished with high quality.
For many explanations, composite crystals are getting to be preferred. These Use a spatially various chemical composition and may be produced with special designs.
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It can be set in some sound mount which also acts being a heat sink. More substantial crystals usually are employed for aspect pumping e.g. with substantial-electricity diode bars.
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。
