Distinctive crystalline supplies are really various about their hardness and various Houses, which identify with which solutions And just how very easily they are often Minimize and polished with top quality.
The medium should have a superior transparency (lower absorption and scattering) during the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the caliber of the material, determined by facts with the fabrication system.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-point out lifetime.
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 utmost possible doping focus can depend strongly about the host materials and its fabrication strategy.
g. a thin disk. As another example, Q-switched lasers get to a higher population density during the higher laser degree and therefore are consequently far more delicate to quenching consequences and Electrical power transfer processes; consequently, a reduce doping density is frequently suitable for these equipment. For prime-ability lasers, lessen doping densities are sometimes accustomed to Restrict the density of warmth generation, Whilst slim-disk lasers work best with remarkably doped crystals. Several laser items tend not to reach the complete overall performance possible for the reason that these types of information haven't been adequately worked out.

A high problems threshold in terms click here of pulse fluence or peak intensity is often essential for prime-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：

It might be oriented for near perpendicular incidence with the laser beam, or at Brewster's angle. It may be preset in some stable mount which also acts to be a warmth sink. More substantial crystals are generally useful for facet pumping e.g. with substantial-electricity diode bars.
In this article you'll be able to post issues and responses. In terms of they get acknowledged because of the writer, they will surface higher than this paragraph together with the creator’s solution. The writer will settle on acceptance according to sure conditions. In essence, The difficulty must be of sufficiently wide desire.
A number of laser crystal elements have been demonstrated wherever some saturable absorber materials is integrated for passive Q switching of a laser.
Of course, it is very desirable that a specified crystal excellent is made constantly, Despite the fact that unique laser patterns might have another sensitivity to substance parameters.
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 concept, a single doesn't have to have a further saturable absorber crystal, so that one particular may perhaps make much more compact Q-switched laser setups with decreased internal parasitic losses. On the other hand, unwelcome Negative effects may occur, including acquiring undesired valence states on the included ions or energy transfers.

It is apparent that distinctive apps bring about really different necessities on laser gain media. This is why, a broad vary of various crystals are employed, and building the ideal preference is important for setting up lasers with optimum performance.
