Stimulated Brillouin Scattering Reflectivity in the Presence of Various Aberrators.
Abstract
The phase-conjugate nature of a light wave reflected by Stimulated Brillouin Scattering was studied to determine the amount of compensation provided by SBS for aberrations in the system. The SBS medium used was CS2 liquid contained in a cylindrical glass cell. Two different types of cell were used: one with a narrow capillary waveguide inside it and another without any type of waveguide. The ability of SBS to correct for aberrators which change the polarization of the beam, focus the beam, or diffract the beam was studied. These aberrators included a sapphire quarter-wave plate, a Cornu Pseudodepolarizer, a cylindrical lens telescope, a single cylindrical lens, over-lapping microscope slides (one-dimensional apertures), and a piece of wire mesh (two-dimensional apertures). The SBS return compensated either partially or completely for all of the aberrators tested. The results also indicated that the cell with the waveguide had a much lower SBS threshold than the other cell.
