Abstract

Stimulated Brillouin scattering (SBS), a nonlinear process in which an intense beam of pumping light propagates in a single mode fiber in such a way as to generate gain for a counterpropagating, frequency-downshifted beam, is presently used in the design of a fiber ring laser gyroscope. In this gyro configuration, two independent, counterpropagating SBS lasers are generated that share the same cavity and frequency, as well as almost the same spectral width. The readout of such a gyro is inherently digital.
