Abstract

A new phase conjugate mirror based on stimulated Brillouin scattering (SBS) in a multimode fiber amplifier is presented. The optical amplification leads to a drastic reduction of the SBS threshold. A peak power threshold of 5 W was detected for a 10 m long Ytterbium doped fiber amplifier. The experimental examinations include the measurements of the phase conjugate fidelity, the temporal behavior of the Stokes pulse and the spectra of the back scattered light.
