The most typical laser-Energetic scarce earth ions and host media together with some usual emission wavelengths are revealed in the next table:
These ions enable the crystal to amplify light-weight on the laser wavelength by way of stimulated emission, when Electrical power is provided towards the crystal by using absorption of pump gentle (�?optical pumping
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。
Which geometry, dopant and doping concentration with the attain medium are most useful count on several factors. The accessible pump source (kind of laser diode or lamp) as well as the envisaged pumping arrangement are essential elements, but the fabric by itself also has some affect. For instance, titanium–sapphire lasers need to be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with comparatively little pump and laser beam diameter, is a lot more acceptable than e.
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。
A large floor excellent is needless to say vital. Specs of surface area flatness will often be better than . This aids to stay away from both scattering losses and wavefront distortions which may degrade the laser's beam good quality. Also, scratch and dig requirements
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。
Laser modeling and simulation can be utilized to reliably figure out the the best possible crystal dimensions, doping density And perhaps values of added parameters.
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。

It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in certain good mount which also functions being a heat sink. Greater crystals are frequently utilized for facet pumping e.g. with high-ability diode bars.
