Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical resources) �?which might be utilised as obtain media for strong-point out lasers. Typically, They can be doped with either trivalent scarce earth ions or transition metallic ions.
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 gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) by using a broad a number of specs. Besides the nicely-recognized materials, revolutionary crystals with excellent properties like Yb:CALGO can open up new horizons for demanding laser purposes. It doesn't matter whether particular person items for R & D reasons are needed or Price-efficient quantities in tiny, medium or significant batches with in-time shipping for your production line are wanted: GWU’s devoted assistance helps you to locate the finest 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 thin disk. As Yet another instance, Q-switched lasers get to the next inhabitants density in the upper laser level and therefore are as a result far more delicate to quenching outcomes and Electricity transfer procedures; thus, a decreased doping density is commonly appropriate for these gadgets. For top-energy lasers, reduced doping densities tend to be accustomed to Restrict the density of heat era, Though thin-disk lasers function very best with highly doped crystals. Many laser products and solutions never get to the total efficiency possible simply because such aspects have not been correctly labored out.
The host crystal is a great deal more than just a method to fix the laser-Energetic ions at certain positions in Room. Numerous Houses in the host product are essential:
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 obvious that distinct programs result in very different prerequisites on laser get media. This is why, a broad variety of various crystals are applied, and generating the correct option is important for setting up lasers with optimum general performance.
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 numerous factors, composite crystals more info are becoming well-liked. These Have got a spatially various chemical composition and will be created with Exclusive designs.
