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 offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a wide selection of specs. Apart from the effectively-founded resources, innovative crystals with outstanding Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Regardless of regardless of whether person pieces for R & D uses are needed or cost-efficient figures in modest, medium or massive batches with in-time shipping and delivery for that output line are desired: GWU’s focused services really helps to locate the most effective core elements in your software.
A higher surface area top quality is not surprisingly crucial. Technical specs of area flatness are often better than . This aids to prevent both equally scattering losses and wavefront distortions that may degrade the laser's beam good quality. Furthermore, scratch and dig requirements
The maximum achievable doping concentration can depend strongly on the host content and its fabrication system.
Laser modeling and simulation can be employed to reliably ascertain the the best possible crystal dimensions, doping density And perhaps values of further 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。
For quasi-three-level laser attain media or simply a few-degree achieve media, a single typically should limit the length to a value which is way too shorter for effective pump absorption, as reabsorption effects would otherwise spoil the effectiveness. For aspect pumping, extra things to consider arrive into play; Moreover productive pump absorption, it's important to get an acceptable spatial condition with the get profile.

GWU-Lasertechnik has over thirty years of practical experience in distributing laser crystals. Opt for GWU to reap the benefits of our vast knowledge and in-industry experience!
With that concept, just one won't want yet another saturable absorber crystal, to ensure a person may possibly make much more compact Q-switched laser setups with decreased inner parasitic losses. Even so, unwelcome Negative effects could also come about, including acquiring unwelcome valence states of your involved ions or Vitality transfers.
