Laser modeling and simulation can be used to reliably decide the optimum crystal Proportions, doping density and possibly values of extra parameters.

The medium ought to have a substantial transparency (small absorption and scattering) while in the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the fabric, determined by aspects of your fabrication procedure.

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the upper-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 most doable doping focus can rely strongly over the host materials and its fabrication method.

g. a skinny disk. As Yet another example, Q-switched lasers attain a better inhabitants density inside the higher laser level and therefore are consequently much more sensitive to quenching effects and Strength transfer procedures; thus, a reduce doping density is usually suitable for these equipment. For top-energy lasers, decrease doping densities in many cases are utilized to Restrict the density of heat technology, Though slim-disk lasers function greatest with highly doped crystals. Quite a few laser merchandise never get to the total efficiency potential for the reason that these kinds of aspects have not been thoroughly worked out.

GWU-Lasertechnik has a lot more than thirty yrs of practical experience in distributing laser crystals. Pick out GWU to benefit from our wide understanding As well as in-subject encounter!

Furthermore, some overall flexibility is shed in experiments if just one can't try out absorbers with diverse thickness or doping concentration, for example, with out 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 might be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be fastened in certain reliable mount which also acts being Laser Crystal a heat sink. Greater crystals are often utilized for facet pumping e.g. with large-electric power diode bars.

The most typical laser-Lively rare earth ions and host media together with some common emission wavelengths are demonstrated in the following desk:

A couple of laser crystal products happen to be demonstrated where some saturable absorber material is included for passive Q switching of a laser.

For several good reasons, composite crystals are getting to be well-liked. These Possess a spatially varying chemical composition and might be built with Unique shapes.

You can find a wide array of crystalline media, which may be grouped according to big atomic constituents and crystalline buildings. Some critical groups of crystals are:

GWU offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) using a broad number of specifications. Besides the well-recognized elements, ground breaking crystals with outstanding properties like Yb:CALGO can open new horizons for demanding laser programs. Despite no matter if particular person pieces for R & D needs are demanded or Expense-successful numbers in little, medium or substantial batches with in-time delivery for the creation line are needed: GWU’s devoted provider helps to discover the most effective core components for your personal application.

It is clear that diverse apps produce pretty different specifications on laser gain media. For this reason, a wide range of various crystals are utilised, and creating the ideal decision is important for constructing lasers with ideal efficiency.

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。
