Laser modeling and simulation may be used to reliably ascertain the ideal crystal dimensions, doping density And maybe values of extra 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 likewise the higher-point out 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。

The utmost possible doping concentration can count strongly about the host material and its fabrication strategy.

g. a thin disk. As One more case in point, Q-switched lasers achieve the next population density from the upper laser degree and so are consequently far more delicate to quenching effects and Electrical power transfer processes; for that reason, a lessen doping density is often appropriate for these products. For top-energy lasers, decrease doping densities will often be used to limit the density of heat era, While slender-disk lasers function ideal with remarkably doped crystals. Lots of laser products usually do not reach the entire effectiveness opportunity because this kind of specifics have not been effectively worked out.

GWU-Lasertechnik has greater than thirty yrs of practical experience in distributing laser crystals. Decide on GWU to gain from our broad knowledge As well as in-discipline encounter!

A high hurt threshold when it comes to pulse fluence or peak depth may be vital for high-Electricity 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：

Which geometry, dopant and doping focus of your obtain medium are most useful depend on numerous things. The accessible pump supply (variety of laser diode or lamp) and also the envisaged pumping arrangement are very important things, but the material itself also has some affect. Such as, titanium–sapphire lasers should be pumped with high intensities, for which the form of a transversely cooled rod, operated with reasonably smaller pump and laser beam diameter, is a lot more appropriate than e.

It may be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in certain good mount which also functions as a heat sink. Bigger crystals are generally utilized for side pumping e.g. with large-electrical power diode bars.

The most typical laser-Energetic exceptional earth ions and host media along with some normal emission wavelengths are proven in the following desk:

Some laser crystal supplies are demonstrated wherever some saturable absorber material is integrated for passive Q switching of the laser.

For numerous good reasons, composite crystals are becoming well-known. These Have got a spatially varying chemical composition and may be designed with special designs.

There is an array of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some critical teams of crystals are:

GWU offers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a broad a number of requirements. read more Aside from the nicely-founded elements, progressive crystals with excellent Attributes like Yb:CALGO can open new horizons for demanding laser purposes. It does not matter regardless of whether individual items for R & D functions are demanded or Expense-efficient figures in compact, medium or massive batches with in-time delivery to the production line are necessary: GWU’s focused support really helps to find the ideal Main elements in your application.

It is clear that different programs cause incredibly different specifications on laser achieve media. This is why, a wide vary of different crystals are used, and creating the best alternative is important for developing lasers with the best possible general performance.

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。
