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 handful of laser crystal components happen to be demonstrated where by some saturable absorber materials is incorporated for passive Q switching of the laser.
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。
All those surfaces which happen to be handed through the laser beam are normally either oriented at Brewster's angle or have an anti-reflection coating.

The medium should have a higher transparency (minimal absorption and scattering) check here in the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the caliber of the fabric, based on aspects from the fabrication method.
With That idea, one isn't going to need a further saturable absorber crystal, to ensure 1 may perhaps make far more compact Q-switched laser setups with lessen interior parasitic losses. Nevertheless, undesirable side effects may arise, such as obtaining unwelcome valence states from the involved ions or Power transfers.
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。
