Laser modeling and simulation can be utilized to reliably determine the the best possible crystal dimensions, doping density And maybe values of further 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 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。
For quasi-3-degree laser acquire media or perhaps three-amount obtain media, a single usually needs to Restrict the size to a value which happens to be far too small for productive pump absorption, as reabsorption results would in any other case spoil the general performance. For side pumping, further considerations appear into Perform; Moreover successful pump absorption, it is crucial to get a suitable spatial condition with the attain profile.
g. a skinny disk. As One more case in point, Q-switched lasers achieve a better population density within the upper laser level and therefore are for that reason additional sensitive to quenching effects and Power transfer procedures; for that reason, a reduced doping density is usually suitable for these gadgets. For top-power lasers, decreased doping densities are frequently accustomed to Restrict the density of heat era, although slim-disk lasers function most effective with remarkably doped crystals. Numerous laser merchandise usually do not reach the whole overall performance likely mainly because such aspects have not been effectively worked out.

A superior harm threshold concerning pulse fluence or peak depth can be vital for top-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 incorporate only the most typical host crystals; lots of others exist, which are a lot less regularly utilized.
The most common laser-active exceptional earth ions Laser Crystal and host media along with some standard emission wavelengths are demonstrated in the following table:
Those surfaces that happen to be handed via the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.
Naturally, it is very attractive that a presented crystal good quality is generated continually, Even though diverse laser styles may have a different sensitivity to substance parameters.
There is a wide range of crystalline media, that may be grouped according to big atomic constituents and crystalline structures. Some important groups of crystals are:

GWU features all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) by using a broad assortment of specifications. Aside from the nicely-established components, modern crystals with superb Attributes like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of no matter whether individual items for R & D needs are necessary or Price-effective numbers in tiny, medium or huge batches with in-time delivery with the manufacturing line are essential: GWU’s devoted service helps you to find the best core parts on your software.
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical elements) �?which are made use of as get media for stable-state lasers. Typically, They're doped with both trivalent rare earth ions or transition 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。
