稀土离子掺杂飞秒光纤激光器最新进展

Recent Progress on Rare Earth Doped Femtosecond Fiber Lasers

光纤激光器可分为基于非线性效应的光纤激光器和基于稀土离子受激辐射的掺杂光纤激光器。按照掺杂元素的不同,光纤激光器可以分为掺镱、掺铒、掺铥和掺镨等光纤激光器。针对稀土掺杂飞秒光纤激光器的最新研究进展进行了分析和总结,并给出了各种飞秒光纤激光器的优缺点和未来需要解决的问题,为稀土掺杂飞秒光纤激光器的优化设计提供参考。

Generally fiber lasers are classified as two types according to their principles. One is based on nonlinear effect of silica fiber, and the other is based on the simulated emission of rare earth ions which are doped in the optical fiber, the rare earth elements doped in the fiber are always lanthanide series. The development of femtosecond fiber laser is analyzed and the characterstics of several femtosecond fiber lasers are demonstrated. The idea to resolve the present problems of the femtosecond fiber lasers is ~ave.
