Short pulse and high repetition rate actively Q-switched all-in-fibre laser

摘要

An actively Q-switched, 1.05 ;C;m fibre laser delivering 10 ns pulses with high repetition rate (tunable in the range 100 kHz ¿ 1 MHz) is reported. These are believed to be the shortest pulses and highest repetition rates demonstrated to date from an actively Q-switched allin- fibre laser. Pulse energies between 3 and 28 ;C;J have been achieved directly from the oscillator.
