The commonest laser-Energetic unusual earth ions and host media together with some standard emission wavelengths are shown in the subsequent desk:

激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光,这对某些应用可能有益。

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。

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。

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。

A few laser crystal resources happen to be demonstrated where by some saturable absorber materials is integrated for passive Q switching of the 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。

Those surfaces which are handed from the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.
