Optimization of Mamyshev regenerator for ultrafast pulse generation

Abstract

Fiber based Mamyshev regenerators provide potentially a low cost, pulse-on-demand source with pulse durations down to the hundred femtosecond scale. Based on nonlinear broadening of gain switched diode laser pulses in fiber and consequent pulse shaping methods, these sources could provide an alternative for mode-locked systems. Here we study numerically the properties of such sources in terms of input pulse duration and power as well as various fibers. We show that an optimum operating region can be found for each input parameter combination, that is limited mainly by the onset of spontaneous Raman scattering and optical wave breaking.
