Abstract

In this work, we present a fiber-based setup for femtosecond pulse generation at $\sim910 - 940\;{\rm nm}$ wavelength. Pump pulses from a Mamyshev oscillator with center wavelength at 1036 nm 1 ps duration are amplified and coupled into a photonic crystal fiber forming a soliton at 1051 nm. Due to the nonlinear four-wave mixing process, soliton pulses are converted to 910–940 nm with a few hundred femtosecond pulses with energy up to 0.7 nJ. The proposed design utilizes features of the Mamyshev oscillator, enabling a robust way of generating femtosecond pulses at $\sim910 - 940\;{\rm nm}$.
