摘要

Pumping by rectangular shaped dissipative soliton resonance (DSR) pulses at 1030 nm, selective excitations of Raman Stokes lines of up-to 3rd order with extinction ratio of 8 dB and 5th order with extinction ratio of 4 dB are demonstrated experimentally. The rectangular DSR pulses are generated from a dual-amplifier ytterbium-doped figure-eight mode-lock laser constructed by all 10 μm-core-diameter large-mode-area fibers. By varying the two pump powers, the peak power of the output DSR pulses can be continuously tuned from 10 W to 100 W and 30 W to 200 W respectively for two different lengths of the nonlinear amplification loop mirror inside the cavity. High-frequency components are found correspond to pulse parts in trailing edge when two bandpass filters are used to separate propagated pulse. Consequently, it provides an all-fiber technique to achieve selective excitation of the Raman shift by adjusting the peak power of DSR pulse.
