These tables include only the most typical host crystals; lots of Other individuals exist, which might be much less regularly applied.
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 changeover cross-sections of pump and laser transitions as well as the higher-point out lifetime.

Of course, it is very attractive that a supplied crystal excellent is developed persistently, Though various laser layouts can have a different sensitivity to substance parameters.
The maximum doable doping concentration can count strongly around the host product and its fabrication approach.
A few laser crystal elements have already been shown exactly where some saturable absorber substance is included for passive Q switching of a laser.

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。
The medium ought to have a significant transparency (minimal absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. more info To some extent, this depends upon the standard of the material, based on details on the fabrication procedure.
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be mounted in a few sound mount which also acts as a warmth sink. Much larger crystals tend to be employed for aspect pumping e.g. with large-energy diode bars.
