title: Frequency domain aperture for the gain bandwidth reduction of stimulated Brillouin scattering.
abstract: In this Letter, we propose a novel method based on the inhomogeneous Brillouin gain saturation to reduce the gain bandwidth significantly below its natural value. Based on our first experiments, we report a decrease of the bandwidth in a standard single mode fiber down to 3 MHz.
