Abstract

We analyze both theoretically and experimentally the temporal response of a stimulated Brillouin scattering generator to an harmonically modulated pump beam in a 2.1 km optical fiber. It is shown that at certain frequencies fmin≅fcGm (where m is an integer number and fcG≅c(1-G-1)/2nL are frequencies which depends mainly on the fiber's length L but also on the beam's intensity via G) the first harmonic of the generated Stokes beam is relatively suppressed but never vanishes. These frequencies are considerably smaller than the Brillouin's spectral width (∼20 MHz). Excellent agreement with the analytical model is presented.
