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 superior surface good quality is certainly essential. Specs of floor flatness will often be much better than . This helps to prevent the two scattering losses and wavefront distortions which could degrade the laser's beam good quality. Also, scratch and dig requirements

g. a thin disk. As another illustration, Q-switched lasers arrive at a better inhabitants density within the upper laser stage and they are as a result additional delicate to quenching consequences and Power transfer processes; for that reason, a decreased doping density is commonly suitable for these devices. For high-energy lasers, decreased doping densities will often be utilized to Restrict the density of warmth era, Despite the fact that skinny-disk lasers operate ideal with very doped get more info crystals. Several laser items don't get to the entire functionality prospective since such facts have not been properly labored out.

Several laser crystal products are already shown exactly where some saturable absorber content is included for passive Q switching of a laser.

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

Diverse crystalline supplies are really distinct about their hardness along with other Attributes, which determine with which strategies And the way simply they are often Slash and polished with high quality.

GWU-Lasertechnik has more than 30 many years of knowledge in distributing laser crystals. Decide on GWU to take pleasure in our large knowledge As well as in-subject practical experience!
