  • Patent number: 11326884
    Abstract: A disk resonator is pumped by counterpropagating pump signals to produce corresponding counterpropagating Brillouin laser signals. The pump laser optical frequencies are separated by a frequency offset ??P but excite the same nominal resonator optical mode; the Brillouin laser optical frequencies are separated by a beat frequency ??L with 0<??L<??P. A photodetector receives the Brillouin laser signals and produces an electrical signal at the beat frequency ??L. The frequency offset ??P can be large so enough to prevent locking of the Brillouin laser signals onto a common Brillouin laser frequency. A signal processing system derives from the beat frequency ??L an estimated angular velocity component of the disk optical resonator about an axis substantially perpendicular to the disk optical resonator.
