These tables comprise only the most common host crystals; a lot of Many others exist, which can be a lot less routinely utilized.
These ions enable the crystal to amplify mild on the laser wavelength by way of stimulated emission, when Vitality is supplied towards the crystal via absorption of pump light (�?optical pumping
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。
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。
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：
晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心
A high floor quality is of course essential. Specs of surface flatness tend to be better than . This aids to stop the two scattering losses and wavefront distortions which can degrade the laser's beam high quality. Furthermore, scratch and dig technical specs
The most attainable doping focus can depend strongly over the host materials and its fabrication technique.
Laser modeling and simulation may be used to reliably ascertain the ideal crystal Proportions, doping density And maybe values of further parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is obvious that various applications produce incredibly diverse demands on laser obtain media. For this reason, a wide selection of different crystals are used, and building the best selection is important for setting up lasers with optimum effectiveness.

The medium should have a high transparency (small absorption and scattering) in the wavelength locations of pump and laser radiation, and fantastic optical more info homogeneity. To some extent, this depends upon the quality of the material, determined by details of the fabrication procedure.
It might be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in a few reliable mount which also functions being a warmth sink. Larger sized crystals are usually used for side pumping e.g. with higher-energy diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
