Inverse design of a Mamyshev oscillator with MW peak power by a particle swarm optimization algorithm

Abstract

In this study we demonstrate implementation of a particle swarm optimization algorithm for inverse design of a fiber Mamyshev oscillator. We perform an extensive search in high-dimensional space of cavity parameters to maximize the output pulses’ peak power after external compression. The best obtained pulses have peak power exceeding 2 MW, energy >140nJ, and duration <40fs, and exhibit capabilities of handling ∼75π nonlinear phase accumulation.
