These tables have only the commonest host crystals; many Other individuals exist, which are much less routinely employed.
In this article it is possible to post concerns and remarks. So far as they get recognized by the author, they'll seem over this paragraph together with the author’s answer. The creator will determine acceptance based on certain criteria. Effectively, The difficulty have to be of sufficiently wide curiosity.
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
On top of that, some flexibility is misplaced in experiments if one can't try out absorbers with distinct thickness or doping concentration, by way of example, without the need of exchanging the laser crystal by itself.
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：

A high area high quality is naturally important. Specs of surface area flatness in many cases are better than . This assists in order to avoid both equally scattering losses and wavefront distortions that may degrade the laser's beam high-quality. In addition, scratch and dig technical specs
The utmost possible doping concentration can count strongly within the host product and its fabrication approach.
The host crystal is way more than just a way to repair the laser-Lively ions at specific positions in Place. A number of properties with the host product are important:

For quasi-three-degree laser obtain media or even 3-level get media, a single often has to Restrict the length to a price that is much too limited for efficient pump absorption, as reabsorption outcomes would or else spoil the overall performance. For aspect pumping, additional issues occur into Perform; Apart from productive pump absorption, it's important to get an appropriate spatial form on the get profile.
Different crystalline resources are extremely distinctive regarding their hardness and other Homes, which identify with which strategies And just how easily they are often Minimize and polished with good quality.
The medium ought to have a significant transparency (lower absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, determined by details on the fabrication process.
It may be oriented for near perpendicular incidence from the here laser beam, or at Brewster's angle. It can be fixed in certain good mount which also functions being a heat sink. Greater crystals are often used for facet pumping e.g. with substantial-electrical power diode bars.
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。
