Laser Crystal - An Overview
Blog Article
These tables contain only the most typical host crystals; lots of Other people exist, which happen to be much less usually utilized.
These ions permit the crystal to amplify light at the laser wavelength by means of stimulated emission, when Strength is supplied into 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。
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the higher-state life time.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
Of course, it is vitally attractive that a supplied crystal good quality is developed constantly, Even though different laser models may have a different sensitivity to substance parameters.
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。
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-3-level laser attain media or maybe three-level achieve media, a single often ought to limit the duration to a value which happens to be also shorter for productive pump absorption, get more info as reabsorption consequences would in any other case spoil the general performance. For facet pumping, extra considerations arrive into Enjoy; In addition to productive pump absorption, it can be crucial to acquire a suitable spatial shape in the achieve profile.
Diverse crystalline supplies are really distinct about their hardness along with other Attributes, which decide with which solutions And the way simply they may be Minimize and polished with good quality.
For different factors, composite crystals are becoming preferred. These Use a spatially various chemical composition and can be produced with Exclusive styles.
There is an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some vital teams of crystals are:
