These tables incorporate only the most common host crystals; a lot of Other people exist, which happen to be less frequently used.

These ions help the crystal to amplify gentle on the laser wavelength via stimulated emission, when Electrical power is supplied into the crystal through absorption of pump light (�?optical pumping

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

Also, some flexibility is lost in experiments if one particular cannot try out absorbers with diverse thickness or doping focus, such as, with out exchanging the laser crystal by 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：

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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

g. a thin disk. As A different case in point, Q-switched lasers attain an increased inhabitants density within the upper laser level and so are hence a lot more delicate to quenching consequences and Vitality transfer procedures; as a result, a lessen doping density is more info commonly appropriate for these gadgets. For top-energy lasers, lessen doping densities tend to be used to limit the density of heat generation, Even though thin-disk lasers function very best with extremely doped crystals. A lot of laser products and solutions never get to the entire efficiency prospective because these types of particulars have not been thoroughly worked 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。

For quasi-3-amount laser attain media or maybe a few-amount achieve media, 1 frequently must limit the length to a price which can be as well limited for economical pump absorption, as reabsorption outcomes would otherwise spoil the functionality. For facet pumping, supplemental concerns arrive into Perform; Moreover economical pump absorption, it is important to acquire a suitable spatial shape from the achieve profile.

GWU-Lasertechnik has a lot more than 30 several years of working experience in distributing laser crystals. Choose GWU to take pleasure in our extensive understanding As well as in-area encounter!

There exists a variety of crystalline media, which may be grouped according to big atomic constituents and crystalline buildings. Some vital teams of crystals are:

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
