Limits to the efficiency of beam combination by stimulated Brillouin scattering.
The probability distribution function of the phase difference between two thermal-noise-initiated stimulated Brillouin scattering beams was calculated and measured as a function of the correlation between the noise sources. This correlation is determined by the spatial overlap of the two pump beams. Perfect phase locking of every pair of Brillouin-scattered pulses is shown to be impossible.
