Laser modeling and simulation can be used to reliably identify the ideal crystal dimensions, doping density And maybe values of added 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 changeover cross-sections of pump and laser transitions and also the upper-state lifetime.
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 maximum probable doping focus can depend strongly within the host material and its fabrication method.

A substantial damage threshold with regard to pulse fluence or peak depth may be vital for high-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 may be oriented for near perpendicular incidence on the laser beam, or at Brewster's angle. It might be mounted in certain sound mount which also acts being a warmth more info sink. Much larger crystals are often useful for aspect pumping e.g. with superior-energy diode bars.
Below you could post thoughts and opinions. In terms of they get approved from the writer, they are going to appear higher than this paragraph together with the author’s answer. The writer will choose acceptance depending on particular conditions. Fundamentally, The difficulty have to be of adequately broad interest.
These surfaces that happen to be passed through the laser beam are Generally both oriented at Brewster's angle or have an anti-reflection coating.
Not surprisingly, it is rather appealing that a given crystal high-quality is made consistently, Despite the fact that different laser models may have a special sensitivity to product parameters.
There may be an array of crystalline media, that may be grouped in accordance to special atomic constituents and crystalline constructions. Some essential teams of crystals are:
With That idea, a person will not require yet another saturable absorber crystal, in order that just one may make a lot more compact Q-switched laser setups with decreased interior parasitic losses. Nonetheless, undesired Unwanted effects may additionally happen, such as obtaining unwanted valence states in the concerned ions or Vitality transfers.

Laser crystals are optical crystals �?usually one crystals (monocrystalline optical elements) �?which happen to be applied as acquire media for sound-condition lasers. Most often, They're doped with both trivalent scarce earth ions or changeover metallic 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。
