The most typical laser-active rare earth ions and host media along with some standard emission wavelengths are demonstrated in the subsequent table:
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。
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（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 in addition to the higher-point out lifetime.
GWU presents all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) using a broad number of specifications. Aside from the properly-set up products, revolutionary crystals with excellent Houses like Yb:CALGO can open new horizons for demanding laser apps. Despite whether or not unique parts for R & D uses are essential or Value-effective figures in smaller, medium or substantial batches with in-time delivery for the production line are wanted: GWU’s committed services helps to find the greatest core components to your application.
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
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。

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
For various causes, composite crystals are becoming well-known. These Use a spatially varying chemical composition and might be made with special shapes.
It could be oriented for close to perpendicular incidence with the laser beam, or at Brewster's angle. It can get more info be mounted in certain strong mount which also functions to be a heat sink. More substantial crystals are usually used for aspect pumping e.g. with superior-energy diode bars.
