Abstract

Phase conjugation (PC) via stimulated Brillouin scattering (SBS) is widely used, convenient technique for improving the performance of many pulsed lasers. For laser output energies ~1J, satisfactory performance can generally be achieved using a simple SBS phase-conjugate mirror (PCM) in which the beam to be conjugated is simply focussed into a bulk SBS medium. Exploitating PC in lasers producing output energies >10J requires a PCM that produces good conjugation fidelity at energies >1J.
