Laser modeling and simulation may be used to reliably identify the ideal crystal dimensions, doping density And perhaps values of additional parameters.
The medium must have a significant transparency (low absorption and scattering) inside the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this is determined by the quality of the material, based on facts of the fabrication method.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to 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。
For quasi-a few-stage laser obtain media or perhaps a few-stage obtain media, 1 often really should limit the length to a worth that's also short for effective pump absorption, as reabsorption consequences would usually spoil the functionality. For side pumping, additional factors occur into Engage in; besides successful pump absorption, it is important to get a suitable spatial form of the achieve profile.
g. a thin disk. As A further instance, Q-switched lasers access a greater populace density during the upper laser stage and they are therefore a lot more delicate to quenching consequences and Vitality transfer procedures; as a result, a reduced doping density is often suitable for these equipment. For top-electricity lasers, decreased doping densities in many cases are accustomed to Restrict the density of warmth generation, While slender-disk lasers get the job done most effective with extremely doped crystals. Quite a few laser merchandise usually do not get to the comprehensive get more info functionality prospective since these types of particulars have not been effectively worked out.

A substantial injury threshold in terms of pulse fluence or peak depth might be critical 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 commonest host crystals; a lot of others exist, that happen to be significantly less often made use of.
The most typical laser-Lively uncommon earth ions and host media along with some regular emission wavelengths are proven in the subsequent desk:
Several laser crystal elements are already demonstrated the place some saturable absorber content is integrated for passive Q switching of the laser.
For numerous good reasons, composite crystals have gotten well-known. These have a spatially various chemical composition and will be made with Unique 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 won't have to have yet another saturable absorber crystal, making sure that 1 may well make more compact Q-switched laser setups with decrease inside parasitic losses. Nonetheless, unwanted Unintended effects may arise, including acquiring undesirable valence states from the included ions or Electricity transfers.

It is obvious that different apps bring about pretty diverse needs on laser obtain media. For that reason, a broad range of various crystals are applied, and making the right choice is essential for constructing lasers with the best possible efficiency.
