Picosecond pulse burst generation using cascaded Stimulated Brillouin Scattering in a chalcogenide As2Se3 fiber cavity

摘要

Stimulated Brillouin Scattering (SBS) is an inelastic scattering process that has been exploited for applications ranging from tunable delay, microwave generation to sensing and lasers. The recent demonstration [1] of a frequency comb laser based on cascaded SBS in silica fiber has renewed interest in using SBS to generate ultra-high frequency picosecond pulses [2]. In [1] a broad SBS frequency comb is generated in a long (e.g. kilometres) ring cavity using an erbium doped fiber amplifier (EDFA) as gain medium.
