These tables comprise only the most common host crystals; quite a few others exist, which might be much less usually applied.
Here it is possible to post issues and opinions. As far as they get acknowledged with the writer, they may show up earlier mentioned this paragraph along with the writer’s reply. The author will settle on acceptance depending on specific criteria. In essence, the issue must be of adequately broad interest.
Laser crystals are optical crystals �?normally one crystals (monocrystalline optical supplies) �?which are utilised as gain media for solid-condition lasers. Most often, They may be doped with both trivalent scarce earth ions or transition metal ions.

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 presents all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) with a wide assortment of specs. Apart from the very well-founded materials, modern crystals with fantastic properties like Yb:CALGO can open new horizons for demanding laser apps. Regardless of regardless of whether particular person pieces for R & D reasons are necessary or Price tag-economical quantities in compact, medium or significant batches with in-time shipping for that generation line are required: GWU’s committed support helps to find the ideal core elements 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。
g. a thin disk. As A further instance, Q-switched lasers access a higher populace density during the upper laser degree and so are for that reason extra sensitive to quenching results and Strength transfer procedures; hence, a click here lower doping density is usually appropriate for these units. For prime-power lasers, reduce doping densities are frequently used to Restrict the density of warmth era, Despite the fact that slim-disk lasers perform ideal with hugely doped crystals. A lot of laser merchandise usually do not reach the full performance probable mainly because this sort of particulars have not been properly worked out.
The host crystal is much more than just a way to repair the laser-Lively ions at certain positions in Place. Numerous Qualities with the host product are important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

GWU-Lasertechnik has in excess of thirty decades of experience in distributing laser crystals. Select GWU to gain from our extensive expertise and in-area expertise!
With that concept, one does not need yet another saturable absorber crystal, to make sure that a person may well make far more compact Q-switched laser setups with decrease internal parasitic losses. However, undesired Uncomfortable side effects may additionally happen, which include acquiring unwelcome valence states on the concerned ions or Electrical power transfers.
