Laser modeling and simulation can be employed to reliably decide the optimum crystal Proportions, doping density And perhaps values of additional parameters.
The medium must have a superior transparency (minimal absorption and scattering) from the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the quality of the material, determined by facts of the fabrication method.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the higher-point out life time.
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-a few-level laser obtain media or simply a few-stage attain media, a person typically needs to Restrict the size to a price that's way too limited for productive pump absorption, as reabsorption results would in any other case spoil the general performance. For aspect pumping, extra concerns come into play; In addition to productive pump absorption, it is necessary to get a suitable spatial condition with the obtain profile.

A high harm threshold concerning pulse fluence or peak depth may be significant for high-Electrical power 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 most typical host crystals; quite a few Other people exist, which are a lot less often utilised.
The commonest laser-active rare earth ions and host media together with some usual emission wavelengths are proven in the following table:
Some laser crystal products happen to be demonstrated wherever some saturable absorber material is included for passive Q switching of a laser.
For various reasons, composite crystals have gotten popular. These Have got a spatially different chemical composition and might be designed with Exclusive styles.
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。
With That idea, one particular would not will need an additional saturable absorber crystal, making sure that a single may well make much more compact Q-switched laser setups with decreased Laser Crystal inside parasitic losses. Having said that, unwanted Unwanted effects may arise, like getting unwanted valence states in the included ions or Electricity transfers.
GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) using a wide number of technical specs. Other than the perfectly-founded elements, ground breaking crystals with fantastic Qualities like Yb:CALGO can open new horizons for demanding laser applications. Regardless of no matter whether particular person items for R & D reasons are required or Price tag-successful figures in compact, medium or huge batches with in-time shipping with the manufacturing line are desired: GWU’s dedicated support helps to discover the very best Main factors on your software.
Laser crystals are optical crystals �?generally single crystals (monocrystalline optical materials) �?that happen to be utilized as get media for sound-state lasers. Most often, they are doped with both trivalent uncommon earth ions or changeover metallic ions.
