Laser modeling and simulation can be used to reliably figure out the optimum crystal Proportions, doping density and possibly values of additional parameters.
The medium should have a superior transparency (low absorption and scattering) while in the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this depends on the standard of the material, determined by details with the fabrication method.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-state life time.
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 utmost attainable doping concentration can depend strongly within the host material and its fabrication method.

Also, some versatility is lost in experiments if a single are not able to Check out absorbers with distinct thickness or doping focus, as an example, devoid of exchanging the laser crystal itself.
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 have only the most common host crystals; a lot of Other individuals exist, that are significantly less routinely utilised.
Right here you are able to submit issues and opinions. As far as they get accepted through the author, they'll show up higher than this paragraph together with the author’s remedy. The writer will determine acceptance dependant on specific standards. Effectively, The difficulty should be of sufficiently broad desire.
Those surfaces which can be passed because of the laser beam are Generally possibly oriented at Brewster's angle or have an anti-reflection coating.
Obviously, it is vitally fascinating that a given crystal high quality is generated continuously, Despite the fact that distinct laser types might have another sensitivity to material parameters.
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。

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical products) �?which can be made use of as acquire media for reliable-point out lasers. Generally, They can be doped with possibly trivalent rare earth ions or transition steel ions.
