High power short pulse fiber lasers

摘要

This paper describes characteristics of a short pulse doped rare earth fiber laser and amplifier. We have obtained very stable pico-second and femto-second laser pulses from fiber laser. An all-fiber laser and amplifier of a double-clad fiber are researched in detail. The pulse of 177fs at wavelength of ~1.50um has been got from fiber laser. The energy of single pulse of 153μJ has been obtained after an amplifier of a double-clad fiber at repetition-rate of 30 KHz.
