Supercontinuum generation in singlemode fibers using dissipative soliton resonance pulses at 1560 nm

In this article we explore the possibility of utilizing 1560 nm nanosecond dissipative soliton resonance pulses for generation of supercontinuum radiation in a standard singlemode fiber. The source is based on a non-complex, all-in-fiber dissipative soliton resonance mode-locked laser and two sections of fiber amplifiers, boosting the peak power and pulse energy to 147 W and 0.42 mu J, respectively. Pulses with a repetition rate and pulse duration of similar to 1.01048 MHz and 2.67 ns, respectively, were injected into a standard singlemode fiber (SMF-28, Corning) with lengths between 100 m and 600 m. Induced Stimulated Raman Scattering effect resulted in a broadening of the pulse spectrum from the initial 1560 nm, up to similar to 2100 nm. Our results are the first demonstration of using high-energy nanosecond pulses from a non-complex, all-in-fiber dissipative soliton resonance mode-locked laser in a frequency conversion process in a standard singlemode fiber. The proposed approach delivers an alternative solution to broadband light generation using complex nanosecond laser sources.
