Laser modeling and simulation can be used to reliably determine the ideal crystal dimensions, doping density And perhaps 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 medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the higher-state life span.
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 achievable doping concentration can rely strongly about the host substance and its fabrication method.

A high problems threshold with regards to pulse fluence or peak depth could be important for prime-energy 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：

It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be mounted in a few reliable mount which also functions being a warmth sink. More substantial crystals usually are useful for facet pumping e.g. with significant-electric power diode bars.
Below it is possible to submit concerns and reviews. In terms of they get acknowledged because of the writer, they will surface earlier mentioned this paragraph together with the creator’s remedy. The author will decide on acceptance based upon specified criteria. Effectively, The problem must be of adequately broad fascination.
A couple of laser crystal products have already been shown in which some saturable absorber product is incorporated for passive Q switching of the laser.
For various motives, composite crystals are becoming common. These Have got a spatially varying chemical composition and might be made with Particular styles.
There is an array of crystalline media, which can be grouped according to important atomic constituents and crystalline constructions. Some crucial teams of crystals are:
With That idea, one does not require an extra saturable absorber crystal, in order that one particular may possibly make far more compact Q-switched laser setups with decreased inside parasitic losses. On the other hand, undesired Unintended effects could also click here manifest, for instance acquiring undesirable valence states from the involved ions or Electrical power transfers.
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a wide selection of specifications. Other than the very well-proven supplies, ground breaking crystals with remarkable Homes like Yb:CALGO can open new horizons for demanding laser apps. Irrespective of whether or not unique items for R & D purposes are expected or Expense-economical figures in compact, medium or massive batches with in-time delivery to the production line are essential: GWU’s focused support really helps to find the finest core elements for your personal application.
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical products) �?which can be applied as gain media for reliable-point out lasers. Generally, They can be doped with possibly trivalent rare 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。
