These ions permit the crystal to amplify gentle for the laser wavelength by using stimulated emission, when energy is equipped into the crystal by using absorption of pump light-weight (�?optical pumping
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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-point out life time.
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。
A substantial surface area high quality is not surprisingly crucial. Requirements of area flatness tend to be better than . This helps to stop equally scattering losses and wavefront distortions which might degrade the laser's beam good quality. Additionally, scratch and dig specifications
The maximum probable doping concentration can rely strongly to the host content and its fabrication process.
A few laser crystal elements are already demonstrated where by some saturable absorber substance is incorporated for passive Q switching of the laser.
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。
People surfaces which can be handed because of the laser beam are Typically either oriented at Brewster's angle or have an anti-reflection coating.
Diverse website crystalline supplies are really diverse concerning their hardness together with other Qualities, which identify with which approaches and how simply they can be Minimize and polished with good quality.
For numerous causes, composite crystals have gotten popular. These Possess a spatially various chemical composition and might be designed with special shapes.
There may be a wide range of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline structures. Some crucial teams of crystals are:
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。
