Blog Article
These tables include only the most typical host crystals; several Other people exist, which happen to be considerably less frequently utilised.
In this article it is possible to post thoughts and feedback. So far as they get acknowledged from the writer, they can appear earlier mentioned this paragraph along with the creator’s respond to. The creator will decide on acceptance according to particular requirements. Primarily, the issue should be of adequately broad curiosity.
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。

This is a snap to accomplish: just locate the lock icon in front of the URL while in the tackle bar and drag that for the bookmark toolbar While using the mouse. In case you discover the bookmark entry much too extended, you can proper-click on it to edit the textual content, e.g. using "RP Enc" as an alternative to "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a thin disk. As another illustration, Q-switched lasers achieve a greater populace density within the upper laser amount and are for that reason more sensitive to quenching outcomes and Electrical power transfer processes; hence, a reduce doping density is frequently suitable for these equipment. For top-energy lasers, decrease doping densities tend to be accustomed to Restrict the density of warmth generation, Whilst skinny-disk lasers work finest with remarkably doped crystals. Lots of laser products and solutions never get to the entire efficiency prospective because these types of aspects have not been adequately labored out.
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。
It is apparent that various applications result in really distinct demands on laser achieve media. For that reason, a broad variety of various crystals are made use of, and generating the best decision is essential for developing lasers with ideal functionality.

For various reasons, composite crystals are getting to be well known. These Use a spatially varying chemical composition and can be built with Specific shapes.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in certain stable mount which also functions for a warmth sink. Much larger crystals tend to be useful for aspect pumping e.g. with substantial-electricity diode bars.
