Abstract: An experimental study was made of the suppression of phase noise during propagation of giant ruby laser pulses in short (up to 0.1 m) multimode fiber waveguides. A segment of a fiber waveguide, in which stimulated Brillouin scattering took place, acted as a mirror performing phase conjugation. The dependences of the parameters of the corrected signal on the lengths of both waveguide segments were determined.
