Study of the divergence of stimulated Brillouin scattering
The influence of the phase conjugation effect and the threshold effect of stimulated scattering on the divergence of stimulated scattering was discussed. Compared with the pumping beam, the divergence angles of stimulated Brillouin scattering (SBS) in methanol, ethanol and acetone were reduced to a factor of 3.2, 3.0 and 2.4 while the pulse durations were compressed to 4.3, 4.3 and 2.6. The relation between the divergence angle of the stimulated Brillouin scattering and the pumping energy was obtained.
