Laser modeling and simulation can be used to reliably determine the ideal crystal dimensions, doping density And maybe values of more parameters.
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。
The host crystal is a great deal more than just a means to fix the laser-active ions at specific positions in Room. Many properties with the host materials are important:
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
The most feasible doping concentration can count strongly to the host content and its fabrication strategy.

GWU-Lasertechnik has more than 30 years of encounter in distributing laser crystals. Pick GWU to take pleasure in our huge information As well as in-discipline knowledge!
A substantial problems threshold when it comes to pulse fluence or peak depth is usually vital for high-Vitality amplifiers.
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：

These tables include only the commonest host crystals; quite a few Other individuals exist, which can be considerably less often applied.
The commonest laser-active scarce earth ions and host media together with some usual emission wavelengths are proven in the subsequent desk:
A couple of laser crystal resources are already shown wherever some saturable absorber content is incorporated for passive Q switching of the laser.
Needless to say, it is rather attractive that a presented crystal high-quality is made consistently, although different laser designs may have a special sensitivity to product parameters.
There is certainly a variety of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline structures. Some significant groups of crystals are:
With that concept, a person does not require yet another saturable absorber crystal, so that one could make additional compact Q-switched laser setups with lessen internal parasitic losses. Even so, unwanted Negative effects could also happen, including getting undesired valence states with the associated ions or Power transfers.
GWU offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) by using a broad assortment of requirements. Aside from the very well-established resources, innovative crystals with read more fantastic Homes like Yb:CALGO can open new horizons for demanding laser programs. Irrespective of whether or not personal pieces for R & D applications are expected or Charge-economical quantities in smaller, medium or substantial batches with in-time shipping and delivery for your manufacturing line are necessary: GWU’s focused company helps you to locate the greatest Main parts to your software.
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical components) �?which happen to be utilised as obtain media for stable-state lasers. Usually, They're doped with both trivalent scarce earth ions or transition steel 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。
