Description/Abstract
The generation of high peak power pulses by amplification of the output from a distributed feedback diode laser is demonstrated using a cascade of three erbium-doped fiber amplifiers (EDFAs) separated by an acousto-optic gate. The optimized amplifier chain consisted of two high efficiency single-mode EDFAs pumped with 40 mW at 980 nm, followed by a multimode EDFA pumped with 1.5 W at 978 nm. At low repetition rates, peak output powers of 111 kW and energies of 0.5 mJ at 1.534µm were obtained.
