Short pulse, high power Q-switched fibre laser

Abstract

A high-power, laser-diode pumped, Q-switched fiber laser operating 1.053μm is described which is suitable for use in time-multiplexed fiber sensor applications. The laser emits >1 kW pulses at 1.053μm with 2ns duration at up to 1kHz repetition rates for an absorbed pump power of only 22mW at 810 nm. Tunable Q-switched operation over a 40 nm wavelength range has also been demonstrated.
