Phys. Rev. A 57, 3961–3971 (1998)Nature of intensity and phase modulations in stimulated Brillouin scatteringReceived 14 August 1997; published in the issue dated May 1998 The nature of stimulated Brillouin scattering (SBS) temporal modulations for a focused beam in a finite-length cell with homogeneous medium is examined numerically. The finite phonon lifetime produces deterministic oscillations at the threshold while the inclusion of the random noise as an initiation source of SBS leads to stochastic fluctuations in Stokes intensity and phase. A unified study of both modulations under different parameters is presented. The results indicate a large useful parameter space for excellent Stokes beam quality. © 1998 The American Physical Society URL:
