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。

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：

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 A different instance, Q-switched lasers get to a higher populace density in the upper laser degree and are as a result a lot more delicate to quenching effects and Electrical power transfer processes; consequently, a reduced doping density is often appropriate for these units. For prime-electric power lasers, reduced doping densities are sometimes accustomed to Restrict the density of warmth era, Though slim-disk lasers operate ideal with hugely doped crystals. A lot of laser solutions tend not to reach the total efficiency prospective since this sort of particulars haven't been adequately labored out.

Several laser crystal supplies have been shown exactly where some saturable absorber product is integrated for passive Q switching of the laser.

For quasi-three-degree laser achieve media or maybe a few-amount gain media, a single typically ought to Restrict the size to a price and that is much too short for effective pump absorption, as check here reabsorption results would in any other case spoil the functionality. For aspect pumping, added issues appear into Engage in; Aside from productive pump absorption, it is vital to obtain a suitable spatial shape on the attain profile.

Diverse crystalline supplies are really diverse concerning their hardness and also other Houses, which figure out with which strategies And exactly how easily they can be Minimize and polished with high quality.

GWU-Lasertechnik has more than 30 a long time of working experience in distributing laser crystals. Decide on GWU to benefit from our extensive awareness As well as in-discipline encounter!

With that concept, one won't will need an additional saturable absorber crystal, in order that just one may well make extra compact Q-switched laser setups with lessen inner parasitic losses. Nonetheless, unwelcome side effects may additionally manifest, for instance acquiring unwanted valence states from the concerned ions or energy transfers.

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。
