About this document
Brillouin Laser Linewidth Analysis by Dileepkumar Abhijith is a document available to read on EtoBox.
The document analyzes linewidth narrowing in Brillouin fiber ring lasers theoretically. It shows that the phase noise of the pump laser is transferred to the Stokes wave but is strongly reduced and smoothed by acoustic damping and cavity feedback. A simple analytical relation is derived connecting the full width at half maximum of the Stokes linewidth to the pump laser linewidth. Simulations based on the three-wave model of stimulated Brillouin scattering confirm that the Stokes phase fluctuations are stron
