摘要：

We have demonstrated an all fiber, single-frequency 10 ns pulsed high energy and high peak power amplifier. It was capable of reaching 4.6 mJ pulse energy (460 kW peak power) and 2.3 mJ pulse energy (230 kW peak power) respectively for 10 ns pulses corresponding to the repetition rate of 5 kHz and 10 kHz. In the power amplifier stage, we used the large-mode-area fiber to avoid the nonlinear effects such as SBS.
