The most common laser-active scarce earth ions and host media together with some normal emission wavelengths are demonstrated in the subsequent desk:

In this article it is possible to post concerns and feedback. In terms of they get accepted by the author, they will look earlier mentioned this paragraph together with the author’s reply. The creator will determine acceptance dependant on specific standards. Primarily, The difficulty need to be of adequately broad interest.

Laser crystals are optical crystals �?commonly one crystals (monocrystalline optical supplies) �?which can be applied as achieve media for strong-state lasers. Typically, They may be doped with possibly trivalent scarce earth ions or transition steel ions.

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：

晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心

A superior area high-quality is certainly essential. Specs of surface area flatness will often be a lot better than . This helps to stay away from the two scattering losses and wavefront distortions which often can degrade the laser's beam top quality. Moreover, scratch and dig requirements

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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。

For quasi-a few-stage laser gain media or even a few-amount gain media, one particular usually must Restrict the size to a value which happens to be far too limited for effective pump absorption, as reabsorption consequences would if not spoil the general performance. For aspect pumping, further things to consider come into Participate in; Moreover efficient pump absorption, it can be crucial to acquire an acceptable spatial shape of your achieve profile.

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 should have a substantial transparency (small absorption and scattering) within the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the standard of the material, determined by aspects on the fabrication course of action.

It may be oriented for in the vicinity of perpendicular incidence in the laser beam, or at Brewster's angle. It could be preset in a few stable mount which also functions as being a website warmth sink. Larger sized crystals are generally useful for facet pumping e.g. with large-electricity diode bars.
