Laser modeling and simulation can be used to reliably establish the optimum crystal dimensions, doping density and possibly 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 and in addition the upper-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。
For quasi-3-level laser gain media or simply 3-level acquire media, a single normally has to limit the duration to a worth which happens to be much too shorter for economical pump absorption, as reabsorption effects would normally spoil the efficiency. For aspect pumping, supplemental issues arrive into Enjoy; besides effective pump absorption, it is vital to obtain a suitable spatial form in the achieve profile.

GWU-Lasertechnik has more than 30 several years of experience in distributing laser crystals. Pick GWU to reap the benefits of our huge understanding As well as in-industry expertise!
Also, some flexibility is misplaced in experiments if one particular simply cannot Check out absorbers with various thickness or doping concentration, as an example, devoid of exchanging the laser crystal by 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 consist of only the commonest host crystals; a lot of Other folks exist, which might be a lot less usually employed.
The most common laser-Lively unusual earth ions and host media together with some standard emission wavelengths are demonstrated in the following desk:
A handful of laser crystal products have been shown where some saturable get more info absorber product is included for passive Q switching of the laser.
For a variety of motives, composite crystals have become well-known. These Possess a spatially different chemical composition and might be manufactured with Unique styles.

Laser crystals are optical crystals �?ordinarily one crystals (monocrystalline optical elements) �?which might be applied as get media for reliable-state lasers. In most cases, They're doped with possibly trivalent scarce earth ions or transition metal ions.
