Abstract
Title: Enhanced Stability Optical Fiber Resonator The invention relates to an optical resonator (1) comprising a laser source (100) emitting a main laser beam (P) and a multiplexing module (200) configured to spatially separate a portion of the main laser beam (P), referred to as the stabilizing laser beam (S), from the remaining beam. The resonator includes a resonance cavity (300) configured to cause interference between each beam (P, S), thereby generating a modulated main laser beam (P*) and a modulated stabilizing laser beam (S*). A stabilization module (400) reduces the difference between a frequency of the stabilizing laser beam and a frequency of the modulated stabilizing laser beam. The main laser beam and the stabilizing laser beam propagate, at least within the resonance cavity, in an optical fiber using spatial multiplexing.Figure for the abridged version: Fig.1A.
