The commonest laser-Energetic exceptional earth ions and host media along with some regular emission wavelengths are proven in the subsequent desk:
These ions allow the crystal to amplify mild in the laser wavelength through stimulated emission, when Electricity is equipped towards the crystal by way of absorption of pump light (�?optical pumping
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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
GWU provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a broad a number of technical specs. Apart from the properly-founded materials, innovative crystals with outstanding properties like Yb:CALGO can open new horizons for demanding laser apps. Irrespective of whether or not person items for R & D purposes are essential or cost-effective numbers in smaller, medium or significant batches with in-time delivery to the creation line are essential: GWU’s get more info committed support really helps to discover the best Main parts in your software.
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。
The most doable doping concentration can rely strongly within the host content and its fabrication system.
Laser modeling and simulation can be used to reliably establish the the best possible crystal Proportions, doping density And perhaps values of added 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。
It is apparent that diverse purposes result in incredibly distinctive needs on laser achieve media. For that reason, a wide array of different crystals are utilised, and earning the right preference is important for constructing lasers with ideal performance.
Diverse crystalline components are certainly different about their hardness and other properties, which decide with which solutions And the way quickly they can be cut and polished with top quality.
GWU-Lasertechnik has much more than thirty many years of experience in distributing laser crystals. Select GWU to gain from our huge expertise As well as in-subject expertise!
You can find a wide range of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline buildings. Some vital teams 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。
