SYSTEMS AND METHODS FOR STABILIZED STIMULATED BRILLOUIN SCATTERING LASERS WITH ULTRA-LOW PHASE NOISE

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for stabilized stimulated Brillouin scattering lasers with ultra-low phase noise.SOLUTION: In one embodiment, a method for producing a Stimulated Brillouin Scattering (SBS) beam comprises the steps of: generating laser light from a tunable laser source; splitting the laser light into a first light beam and a second light beam; creating a phase modulated light beam by applying a phase modulation to the first light beam; locking a frequency of the laser light to a frequency of a ring cavity using the phase modulated light beam and a Pound-Drever-Hall servo loop coupled to the tunable laser source; coupling the second light beam into the ring cavity in a direction of travel opposite to that of the phase modulated light beam; generating the Stimulated Brillouin Scattering light beam in the ring cavity from the second light beam; and outputting the Stimulated Brillouin Scattering light beam.
