Laser modeling and simulation can be employed to reliably determine the optimum crystal dimensions, doping density and possibly values of additional parameters.
The medium should have a superior transparency (small absorption and scattering) in the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this depends upon the caliber of the material, based on aspects in the fabrication procedure.
The host crystal is far more than just a method to fix the laser-active ions at specific positions in Place. A variety of properties on the host substance are very important:
This is easy to perform: just find the lock icon before the URL inside the address bar and drag that on the bookmark toolbar While using the mouse. In case you find the bookmark entry also prolonged, you are able to correct-click it to edit the textual content, e.g. making use of "RP Enc" as opposed to "RP Photonics Encyclopedia".
For quasi-3-level laser obtain media or even a few-stage gain media, just one typically should limit the size to a value which happens to be way too brief for effective pump absorption, as reabsorption consequences would otherwise spoil the performance. For aspect pumping, supplemental concerns appear into play; Aside from successful pump absorption, it is vital to acquire an acceptable spatial condition on the attain profile.

These tables comprise only the commonest host crystals; quite a few Many others exist, that happen to be a lot less frequently applied.
Here it is possible to submit concerns and reviews. So far as they get recognized by the author, they are going to surface previously mentioned this paragraph together with the creator’s respond to. The author will decide on acceptance according to particular requirements. In essence, The problem should be of adequately wide interest.
A handful of laser crystal supplies are actually demonstrated where by some saturable absorber materials is included for passive Q switching of the laser.
For a variety of motives, composite crystals have gotten popular. These Have got a spatially various chemical composition and may be built with Distinctive 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。

It is obvious that various applications lead get more info to pretty unique necessities on laser achieve media. Because of this, a wide range of different crystals are made use of, and generating the correct option is important for constructing lasers with the best possible functionality.
