摘要：
We report a wide bandwidth (Delta lambda=8 nm) optical pulsed MOPA (master oscillator power amplifier) source emitting 11.23 mJ pulses (1.25 MW peak power) in the wavelength centered at (lambda=1064 nm). Pulse duration and repetition rate were 9 ns and from 10 Hz to 100 Hz, respectively. In order to suppress amplified spontaneous emission (ASE), multi-stage pulse pump technology is applied. And the large core diameter (90 mu m) and wide bandwidth ensures the high peak power and energy output. (C) 2012 Published by Elsevier B.V.
