Experimental study demonstrates noise suppression and 102.3 W pulse generation in an erbium-fiber laser, highlighting potential for long-distance satellite communications.
Key Points
To develop a gain-dispersion-managed nonlinear pre-amplification technique that simultaneously suppresses phase and intensity noise to enable high-power pulse scaling in erbium-fiber lasers.
Designed a gain-dispersion-managed nonlinear pre-amplifier stage to mitigate phase and intensity noise prior to power scaling.
Seeded a high-power erbium-doped fiber amplifier at an 85.69 MHz repetition rate and compressed output pulses using a grating-pair compressor.
Generated polarized pulses with 102.3 W average power and 1.19 µJ pulse energy, which were subsequently compressed to 380 fs.
Achieved near-linear power scaling with a slope efficiency of approximately 40% in the high-power amplifier without observable saturation.
