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 and likewise the higher-state lifetime.
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 substantial area high quality is obviously critical. Technical specs of floor flatness are sometimes a lot better than . This can help to stop both scattering losses and wavefront distortions which can degrade the laser's beam high-quality. Also, scratch and dig technical specs
g. a thin disk. As A further example, Q-switched lasers attain the next inhabitants density inside the higher laser degree and therefore are consequently extra delicate to quenching outcomes and Power transfer processes; for that reason, a decrease doping density is commonly suitable for these gadgets. For top-electrical power lasers, decreased doping densities are often used to Restrict the density of warmth technology, While slim-disk lasers get the job done finest with remarkably doped website crystals. Quite a few laser products will not get to the comprehensive functionality prospective because these information have not been thoroughly labored out.
The host crystal is far more than simply a means to repair the laser-active ions at selected positions in Area. A number of Homes in the host product are crucial:
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 is apparent that unique purposes produce extremely distinct specifications on laser obtain media. This is why, a wide range of different crystals are utilized, and earning the correct decision is important for developing lasers with the best possible functionality.
Various crystalline resources are very diverse concerning their hardness and also other Qualities, which establish with which procedures And the way easily they may be Reduce and polished with high quality.
GWU-Lasertechnik has in excess of thirty years of expertise in distributing laser crystals. Opt for GWU to take advantage of our broad understanding and in-field experience!
There is certainly a wide range of crystalline media, which may be grouped according to big atomic constituents and crystalline structures. Some important groups of crystals are:
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
