These ions enable the crystal to amplify gentle for the laser wavelength by means of stimulated emission, when Vitality is provided into the crystal by using absorption of pump mild (�?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。
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。
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：
GWU offers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) which has a broad range of specifications. Moreover the properly-founded supplies, progressive crystals with excellent Houses like Yb:CALGO can open new horizons for demanding laser apps. Regardless of whether or not unique parts for R & D purposes are demanded or Price-productive quantities in modest, medium or huge batches with in-time shipping for your creation line are required: GWU’s focused assistance helps you to discover the most effective core components to your application.
Certainly, it's very desirable that a specified crystal good quality is produced regularly, While unique laser layouts might have a distinct sensitivity to content parameters.
The utmost probable doping focus can depend strongly on the host materials and its fabrication process.
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。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
For quasi-a few-amount laser attain media or even three-stage attain media, 1 normally should Restrict the duration to a price and that is also shorter for productive pump absorption, as reabsorption effects would usually spoil the general performance. For aspect pumping, further concerns arrive into Perform; In addition to efficient pump absorption, it can be crucial to acquire an appropriate spatial form from the 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 ought to have a higher transparency (low absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this relies on the standard of the material, based on aspects in the fabrication method.
It may be oriented for near perpendicular incidence with the laser beam, or at Brewster's angle. It could be fastened in some strong mount which also here acts like a warmth sink. Much larger crystals are often used for aspect pumping e.g. with superior-power diode bars.
