Laser modeling and simulation may be used to reliably establish the ideal crystal Proportions, doping density And perhaps 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 changeover cross-sections of pump and laser transitions and also the higher-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 a few-stage achieve media, one particular usually has to limit the duration to a price that is as well shorter for successful pump absorption, as reabsorption outcomes would in any other case spoil the overall performance. For side pumping, further things to consider appear into Perform; besides successful pump absorption, it is vital to acquire an appropriate spatial condition in the attain profile.

Furthermore, some flexibility is missing in experiments if a single cannot Check out absorbers with diverse thickness or doping concentration, such as, with no 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：

It may be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It might be fixed in some strong mount which also acts like a heat sink. Much larger crystals tend to be used for facet pumping e.g. with high-energy diode bars.
In this article you could post queries and feedback. As far as they get recognized because of the writer, they'll surface earlier mentioned this paragraph together with the creator’s remedy. The author will decide on acceptance dependant on specified criteria. Essentially, The problem should be of adequately broad desire.
Individuals surfaces which are handed from the laser beam are Ordinarily either oriented at Brewster's angle or have an anti-reflection coating.
For several factors, composite crystals have gotten well-liked. These have a spatially varying chemical composition and can be created with Distinctive shapes.
You can find a wide range of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some crucial groups of crystals are:

GWU provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a broad number of specifications. Other than the properly-set up materials, ground breaking crystals with fantastic Qualities like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of irrespective of whether particular person pieces for R & D applications are necessary or cost-successful numbers in smaller, medium or big batches with in-time supply for your output line are essential: GWU’s dedicated provider really helps to find the greatest core here parts on your software.
Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical supplies) �?that are made use of as achieve media for strong-condition lasers. Usually, They can be doped with both trivalent rare earth ions or changeover metal 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。
