Abstract :
Generation of nanosecond pulses with 55-mJ energy and 4.8-MW peak power are demonstrated in a multistage fiber amplifier system, which is seeded with 10-nm broadband pulses from a superluminescence diode. The pulses are at low repetition of 10 Hz and with width of 10 ns. High energy and high peak power for nanosecond pulses are obtained simultaneously from fiber amplifier. In particular, the peak power is at least two times the previous peak power for nanosecond pulses.
