Paper Abstract

We solved the three coupled partial differential equations in transient regime for the probe-pump Brillouin sensor to explain the sub-peaks in Brillouin loss spectra, which have been experimentally observed. We discovered that the Fourier spectrum of the pulsed signal and the off-resonance oscillation attributed to sub-peaks. The off-resonance oscillation at frequency [v - vB] is the oscillation in the Brillouin time domain when the beat frequency v of the two counter-propagating laser beams does not match the local Brillouin frequency vB. This is important in differentiating the sub-peaks from strain/temperature peaks.
