An ultra-low repetition rate high energy 200 ns Er:Yb co-doped fiber laser has been developed by using a master oscillator power amplifier configuration at an eye-safe 1.53 μm wavelength . A modulated pump scheme was used to suppress ASE accumulation between pulse intervals. Combined with pulse shaping technology to mitigate pulse narrowing effect and SBS effect, a maximum of 480 μJ pulse energy was obtained. In the stable, long-term running mode, pulse energy up to 204 μJ, were obtained with pulse durations of 200 ns at Hz level.
