These tables include only the most typical host crystals; many Other folks exist, that are fewer often employed.
These ions allow the crystal to amplify light at the laser wavelength by using stimulated emission, when Electrical power is provided towards the crystal by means of absorption of pump mild (�?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（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 and in addition the higher-state life time.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
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。
A few laser crystal resources have been demonstrated where some saturable absorber content is included for passive Q switching of a 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。
For quasi-three-amount laser achieve media or perhaps a few-amount obtain media, 1 normally has to Restrict the length to a price which can click here be much too small for effective pump absorption, as reabsorption outcomes would otherwise spoil the effectiveness. For facet pumping, further things to consider come into Perform; Moreover efficient pump absorption, it is necessary to get an acceptable spatial shape from the obtain profile.
Different crystalline elements are incredibly distinctive about their hardness along with other Attributes, which decide with which solutions And the way simply they may be Reduce and polished with high quality.
