Passive optimization of pump noise transfer function by narrow band-pass filtering in femtosecond fiber lasers
Fig. 1. Configuration of the RIN transfer function characterization system. YbF, ytterbium-doped fiber; Q, quarter waveplate; H, half waveplate; ISO, isolator; F, band-pass filter; GP, grating pair; LUT, laser under test; TA, tunable attenuator.
Fig. 2. (a) RIN of the pump LD with (red and green) and without (gray) white noise modulation. (b) RIN of the LUT with (red and green) and without (gray) white noise modulation. (c) Transfer function of the RIN measured by applying 3 mW (green) and 6 mW (red) white noise modulation.
