Stable dual-wavelength fiber laser utilizing tapered-EDF as comb filter in hybrid Raman-EDF gains

Abstract

A dual-wavelength hybrid Raman-erbium doped fiber ring laser is proposed and demonstrated. By tapering a section of erbium doped fiber ends with two-taper successively, the fiber laser can lase two wavelengths at 1563.08 nm (laser 1) and 1589.5 nm (laser 2). This dual wavelengths output exhibits a good performance having the side mode suppression ratio over… (More)
