The commonest laser-Energetic unusual earth ions and host media along with some usual emission wavelengths are proven in the following desk:
These ions allow the crystal to amplify light-weight for the laser wavelength by using stimulated emission, when Vitality is equipped on the crystal by means of absorption of pump light (�?optical pumping
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。

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。
Of course, it's very desirable that a supplied crystal high quality is developed constantly, although unique laser models might have a different sensitivity to materials parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Some laser crystal products are actually shown wherever some saturable absorber material is integrated for passive Q switching of a laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
For quasi-3-degree laser get media or simply a few-degree attain media, one normally should Restrict the size to a worth which can be much too small for efficient pump absorption, as reabsorption click here outcomes would if not spoil the functionality. For aspect pumping, more factors appear into Perform; Aside from economical pump absorption, it is important to obtain a suitable spatial form on the obtain 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。
GWU-Lasertechnik has much more than 30 decades of knowledge in distributing laser crystals. Choose GWU to reap the benefits of our broad know-how As well as in-field encounter!
There is certainly a wide range of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline constructions. Some critical teams of crystals are:
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。
