Laser modeling and simulation may be used to reliably figure out the optimum crystal Proportions, doping density and possibly values of supplemental parameters.
The medium ought to have a high transparency (lower absorption and scattering) during the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by specifics on the fabrication system.
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 most attainable doping focus can rely strongly over the host content and its fabrication method.

A large harm threshold with regards to pulse fluence or peak depth is often critical for high-Strength 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 include only the commonest host crystals; quite a few Other folks exist, which are less frequently employed.
The most typical laser-Energetic exceptional earth ions and host media along with some usual emission wavelengths are demonstrated in the subsequent table:
A handful of laser crystal materials are actually shown in which some saturable absorber materials is included for passive Q switching of the laser.
For several reasons, composite crystals are getting read more to be preferred. These Use a spatially various chemical composition and can be designed with Exclusive designs.
You can find a wide range of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some important teams of crystals are:
With that concept, just one would not have to have an extra saturable absorber crystal, in order that just one might make far more compact Q-switched laser setups with lessen internal parasitic losses. Even so, unwelcome Negative effects could also come about, including getting undesirable valence states on the included ions or Electrical power transfers.
GWU presents all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a broad a number of specifications. In addition to the nicely-established materials, progressive crystals with remarkable Attributes like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of no matter whether personal pieces for R & D purposes are demanded or cost-effective numbers in small, medium or large batches with in-time shipping to the manufacturing line are desired: GWU’s committed provider helps you to find the very best Main parts for your personal application.
Laser crystals are optical crystals �?normally one crystals (monocrystalline optical elements) �?which can be made use of as acquire media for reliable-state lasers. Usually, they are doped with either trivalent exceptional earth ions or transition steel 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。
