Abstract

We present a fiber master oscillator power amplifier system designed to meet stringent requirements of large-scale laser facility front-end sources. A strictly single-mode beam without spatial phase, narrow-bandwidth nanosecond pulse amplification up to 20 μ J is obtained with more than 40 dB optical signal-to-noise ratio, 30 dB polarization extinction ratio, and sub-nanosecond resolution temporal shaping. Experimental results are in excellent agreement with numerical simulations including amplified spontaneous emission. Such a system could advantageously replace cumbersome bulky solid systems.
