Listed here you can post queries and remarks. So far as they get approved through the author, they can surface over this paragraph together with the writer’s answer. The creator will settle on acceptance depending on specific standards. Primarily, the issue need to be of adequately broad desire.
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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 carry out: just discover the lock icon before the URL during the tackle bar and drag that for the bookmark toolbar Using the mouse. In the event you discover the bookmark entry far too very long, you'll be able to appropriate-click it to edit the textual content, e.g. employing "RP Enc" as opposed to "RP Photonics Encyclopedia".
GWU presents all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) with a broad number of requirements. In addition to the perfectly-set up elements, revolutionary crystals with exceptional properties like Yb:CALGO can open up new horizons for demanding laser purposes. Regardless of no matter whether specific parts for R & D reasons are demanded or Expense-economical numbers in smaller, medium or significant batches with in-time supply for that generation line are essential: GWU’s devoted services really helps to find the best core factors on your application.
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 instance, Q-switched lasers arrive at a greater inhabitants density in the higher laser degree and are hence much more delicate to quenching effects and Strength transfer processes; hence, a decrease doping density is commonly appropriate for these equipment. For website top-electric power lasers, decrease doping densities in many cases are accustomed to Restrict the density of heat technology, Though slender-disk lasers work very best with remarkably doped crystals. Several laser solutions tend not to get to the entire effectiveness probable for the reason that this kind of information haven't 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。
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-stage laser obtain media or even 3-level get media, a single generally has to Restrict the length to a value that's way too shorter for successful pump absorption, as reabsorption effects would in any other case spoil the general performance. For facet pumping, more concerns occur into Perform; Aside from successful pump absorption, it is crucial to get an appropriate spatial condition on the obtain profile.

GWU-Lasertechnik has in excess of 30 many years of practical experience in distributing laser crystals. Pick out GWU to reap the benefits of our broad awareness and in-subject encounter!
There's a variety of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline structures. Some crucial groups of crystals are:
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。
