  We propose a method for generating cascaded forward Brillouin scattering
(CFBS), based on a counter-propagated pump-probe technique, utilizing backward
stimulated Brillouin scattering as its seed. The CFBS, induced by forward
stimulated Brillouin scattering (FSBS), is generated via the energy transfer
from the probe light to other acoustic resonance frequencies. Experimental
results for the CFBS generated in a 390-m-long highly nonlinear fiber indicate
that it has a high signal-to-noise ratio (SNR) and that the center frequencies
of its acoustic resonance peaks agree with theoretical values. The sensing
properties of the generated CFBS were also verified.
