ABSTRACT:
A Brillouin ring laser has a laser source, a resonator ring, a fiber optical coupler arrangement for coupling light waves from the laser source with opposite directions of propagation into the resonator ring. The coupled-in light waves have an intensity to cause acoustic waves in the resonator ring. Thereby Brillouin light waves propagating in opposite directions in the resonator ring are generated by Brillouin scattering of the coupled-in light waves at the acoustic waves. The ring laser has detectors and a coupler arrangement for the coupling-out of such Brillouin light waves propagating in opposite directions in the resonator ring and for superimposing the coupled-out Brillouin light waves at the detectors. The fiber optic coupler arrangement has a first leg and a second leg, the legs being coupled through a coupler with the resonator ring, and a six-port coupler, which couples the first and second legs with a pump fiber exposed to a laser light beam from the laser source. The first leg, with its end remote from the resonator ring, extends to a first detector, and the second leg extends to a second detector. The detectors provide detector signals, which are applied to a direction discriminator circuit for generating a directional signal indicative of the direction of rotary movement of the resonator ring.
