The most common laser-Lively exceptional earth ions and host media along with some typical emission wavelengths are shown in the next desk:

These ions allow the crystal to amplify gentle at the laser wavelength by means of stimulated emission, when Electrical power is equipped on the crystal through absorption of pump light-weight (�?optical pumping

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：

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 Yet another illustration, Q-switched lasers achieve an increased population density within the upper laser degree and they are thus additional delicate to quenching outcomes and Electrical power transfer procedures; as a result, a reduced doping density is commonly suitable for these gadgets. For high-ability lasers, reduced doping densities will often be accustomed to limit the density of warmth generation, Whilst skinny-disk lasers work most effective with really doped crystals. A lot of laser items never reach the whole efficiency opportunity since these kinds 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。

For quasi-three-stage laser acquire click here media or perhaps 3-degree obtain media, just one normally must limit the length to a value which is too shorter for productive pump absorption, as reabsorption outcomes would if not spoil the efficiency. For side pumping, added issues occur into Engage in; Moreover efficient pump absorption, it is vital to get a suitable spatial condition on the gain 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。

For a variety of reasons, composite crystals have become common. These have a spatially different chemical composition and will be designed with special shapes.

Using our advertising deal, it is possible to Exhibit your emblem, further down below your solution description, and these will been found by several photonics specialists.

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
