These tables consist of only the commonest host crystals; a lot of Other people exist, which are considerably less often utilized.
These ions enable the crystal to amplify gentle at the laser wavelength by way of stimulated emission, when Power is equipped to the crystal through absorption of pump light-weight (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
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：
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
A large surface area excellent is needless to say important. Technical specs of surface area flatness are often a lot better than . This assists to stay away from equally scattering losses and wavefront distortions which may degrade the laser's beam high-quality. Moreover, scratch and dig specifications
g. a skinny disk. As another instance, Q-switched lasers get to the next inhabitants density in the upper laser degree and therefore are for that reason extra delicate to quenching consequences and energy transfer processes; consequently, a reduced doping density is usually appropriate for these units. For prime-electricity lasers, decrease doping densities in many cases are utilized to Restrict the density of heat era, Though thin-disk lasers function very best with extremely doped crystals. Many laser products and solutions don't reach the full overall performance opportunity mainly because this sort of particulars haven't been adequately worked out.
A few laser crystal products are already demonstrated wherever some saturable absorber materials is included for passive Q switching of a laser.

For quasi-three-level laser obtain media or perhaps a few-degree gain media, one typically has to limit the length to a price that's far too shorter for economical pump absorption, as reabsorption consequences would otherwise spoil the overall performance. For side pumping, extra concerns arrive into play; In addition Laser Crystal to efficient pump absorption, it's important to obtain an acceptable spatial condition on the achieve profile.

The medium must have a substantial transparency (very low absorption and scattering) during the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this depends on the quality of the material, determined by details from the fabrication approach.
