Spectrum suppression of high-peak-power pulsed single-frequency fiber MOPA by manipulation of pulse shape and corresponding nonlinear phase shifting
In this paper, the spectrum suppression of a nanosecond pulsed single-frequency all-fiber amplifier was realized by manipulation of pulse shape and self-phase-modulation-induced nonlinear phase shifting. Near-transform-limited linewidth of 80MHz was obtained at a peak power of 37.5kW for a 7.9-ns pulsed single-frequency laser at 1064nm.
