These tables contain only the most typical host crystals; lots of Other individuals exist, which happen to be considerably less usually applied.
These ions enable the crystal to amplify gentle with the laser wavelength by way of stimulated emission, when energy is provided towards the crystal by using absorption of pump mild (�?optical pumping
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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。
A high surface top quality is certainly essential. Specs of floor flatness will often be much better than . This can help to stay away from both scattering losses and wavefront distortions which may degrade the laser's beam top quality. Furthermore, scratch and dig specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
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。
For quasi-3-level laser attain media or maybe three-level get media, one particular frequently really should limit the size to a more info value that's as well small for effective pump absorption, as reabsorption outcomes would otherwise spoil the effectiveness. For aspect pumping, additional factors appear into play; Apart from successful pump absorption, it is important to obtain a suitable spatial form with the attain profile.

The medium must have a higher transparency (small absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the quality of the material, based on specifics from the fabrication course of action.
Making use of our promoting offer, it is possible to display your brand, even further beneath your products description, and these will been observed by lots of photonics pros.
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。
