Abstract

An actively Q-switched, 1.05 µm 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 all-in-fibre laser. Pulse energies between 3 and 28 µJ have been achieved directly from the oscillator. [ABSTRACT FROM AUTHOR]

Abstract

Co- and counter-propagative pumping schemes were experimentally compared for the amplification of ultra-short optical pulses. According to pumping direction it is shown that optical pulses with a duration of 75 fs and 100 mW of average output power can be obtained for co-propagative pumping, while pulse duration is never shorter than 400 fs for the counter-propagative case.
