摘要

Noise like pulses having pedestal of 690 fs and spike of 59.6 fs were generated in a nonlinear Yb-doped fiber amplification system. The seed source is a mode-locked Yb-doped fiber laser by nonlinear polarization rotation, and dissipative soliton pulses were obtained in it. Then the dissipative soliton pulses passed through a 7.6-m dispersive fiber to enhance the dispersion and nonlinearity. On further the dissipative soliton pulses were launched into an Yb-doped fiber nonlinear amplifier, and stable noise like pulses with a pedestal of 6.26 ps and spike of 227 fs were achieved. Finally, by a grating pair, the pedestal and spike of the noise like pulses were effectively compressed to 690 fs and 59.6 fs, respectively. To the best of our knowledge, this is the shortest pedestal demonstrated in noise like pulses operating at 1 µm.
