These tables incorporate only the most common host crystals; a lot of Other people exist, which happen to be considerably less routinely utilized.
Below you are able to submit issues and comments. As far as they get acknowledged because of the creator, they will appear over this paragraph together with the author’s respond to. The author will settle on acceptance determined by specified standards. Fundamentally, The problem have to be of sufficiently broad desire.
Laser crystals are optical crystals �?commonly single crystals (monocrystalline optical elements) �?that happen to be made use of as achieve media for good-state lasers. Typically, They're doped with both trivalent scarce earth ions or changeover metallic ions.
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。
The host crystal is considerably more than simply a means to fix the laser-Energetic ions at sure positions in Area. Quite a few Attributes from the host substance are important:
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。
Those surfaces that happen to be passed by the laser beam are Usually possibly oriented at Brewster's angle or have an anti-reflection coating.

The medium ought to have a large transparency (reduced absorption and scattering) in the wavelength areas of pump and laser radiation, and great optical homogeneity. To some more info extent, this depends on the standard of the material, determined by details of your fabrication approach.
With that concept, 1 does not require an additional saturable absorber crystal, in order that a single could make a lot more compact Q-switched laser setups with reduced internal parasitic losses. Having said that, undesired Unintended effects may take place, such as acquiring unwelcome valence states in the associated ions or Vitality transfers.
