Mode-locked Nd-doped fiber laser at 930  nm

We report on a passively mode-locked neodymium-doped oscillator featuring a W-type fiber operating at 930 nm. Two different laser configurations with and without dispersion management are investigated to generate high-energy similaritons. Chirped pulses with 2.2 nJ energy that can be compressed to 126 fs are generated in the dispersion-managed cavity. The ANDI-fiber laser delivers parabolic pulses with 5.2 ps duration that can be compressed to 146 fs.
