Laser modeling and simulation may be used to reliably identify the optimum crystal Proportions, doping density and possibly values of further parameters.
The medium should have a large transparency (minimal absorption and scattering) inside the wavelength regions of pump and laser radiation, and great optical homogeneity. To some extent, this is dependent upon the standard of the material, determined by aspects from the fabrication process.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-condition 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。
For quasi-three-level laser achieve media or maybe a few-level get media, one particular often needs to limit the duration to a value which can be much too quick for productive pump absorption, as reabsorption results would otherwise spoil the overall performance. For aspect pumping, more considerations come into Engage in; Aside from successful pump absorption, it can be crucial to obtain an acceptable spatial form on the get profile.

GWU-Lasertechnik has a lot more than thirty many years of expertise in distributing laser crystals. Pick GWU to benefit from our vast expertise and in-discipline practical experience!
A high destruction threshold in terms of pulse fluence or peak depth could be critical for prime-energy 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：

It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in some solid mount which also acts to be a warmth sink. Larger sized crystals usually are employed for side pumping e.g. with high-electrical power diode bars.
The commonest laser-Lively uncommon earth ions and host media together with some common emission wavelengths are demonstrated in the following table:
A number of laser crystal products are already shown the place some saturable website absorber substance is included for passive Q switching of the laser.
For various causes, composite crystals have gotten well-known. These have a spatially various chemical composition and can be designed with Distinctive designs.

GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) using a broad selection of technical specs. In addition to the effectively-set up resources, ground breaking crystals with outstanding Homes like Yb:CALGO can open new horizons for demanding laser apps. It doesn't matter no matter whether specific pieces for R & D functions are essential or cost-effective figures in little, medium or big batches with in-time shipping for your manufacturing line are desired: GWU’s committed company helps to locate the greatest Main elements for the application.
It is clear that distinct apps bring about really various requirements on laser gain media. Due to this, a broad selection of various crystals are made use of, and making the correct decision is essential for developing lasers with optimum overall performance.
