These tables have only the commonest host crystals; a lot of others exist, that happen to be fewer often utilised.

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。

In addition, some versatility is missing in experiments if one can not try out absorbers with distinct thickness or doping concentration, by way of example, with out exchanging the laser crystal 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：

晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心

A substantial area quality is naturally significant. Technical specs of surface flatness tend to be better than . This aids to stop both of those scattering losses and wavefront distortions that may degrade the laser's beam quality. In addition, scratch and dig specs

g. a skinny disk. As Yet another illustration, Q-switched lasers reach a better populace density in the upper laser degree and so are hence much more sensitive to quenching results and Electrical power transfer procedures; therefore, a reduce doping density is usually suitable for these products. For prime-electric power lasers, lessen doping densities are often utilized to Restrict the density of warmth generation, although slender-disk lasers do the job most effective with remarkably doped crystals. Numerous laser products never get to the total efficiency possible because these information haven't been appropriately worked out.

The host crystal is a lot more than simply a method to repair the laser-Lively ions at particular positions in Room. A variety of Attributes from the host Laser Crystal product are important:

蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力

It is clear that different purposes lead to very different specifications on laser gain media. For this reason, a wide array of various crystals are made use of, and earning the appropriate decision is essential for developing lasers with optimum general performance.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The medium ought to have a superior transparency (reduced absorption and scattering) within the wavelength locations of pump and laser radiation, and good optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by facts from the fabrication course of action.

With That idea, just one won't will need a further saturable absorber crystal, to ensure a single might make more compact Q-switched laser setups with lessen inner parasitic losses. Even so, undesired Negative effects might also manifest, for instance obtaining undesired valence states from the included ions or Power transfers.
