Cas. Deoliveira et al., STIMULATED BRILLOUIN-SCATTERING IN CASCADED FIBERS OF DIFFERENT BRILLOUIN FREQUENCY-SHIFTS, Journal of the Optical Society of America. B, Optical physics, 10(6), 1993, pp. 969-972
Experimental investigations of stimulated Brillouin scattering in two
cascaded single-mode optical fibers with different Brillouin shifts ar
e presented. A fiber Brillouin laser consisting of these two cascaded
fibers is demonstrated. The output of such a laser exhibits two freque
ncies corresponding to the Brillouin-shifted frequencies of two indivi
dual fibers.
