Abstract

The amplification of low repetition rate, 1.534µm pulses from a DFB laser diode to peak output powers of 111kW and energies of 0.5mJ is demonstrated. The optimised amplifier chain comprised two high efficiency single-mode, 980nm (40mW) pumped erbium-doped fibre amplifiers (EDFAs) separated from a multimode, 978nm (1.5W) pumped EDFA by an acousto optic gate.
