Outline of Final Research Achievements

Four-Wave-Mixing (FWM) as a Phase Conjugate (PC) mirror for a beam steering method of inertial laser fusion was proposed. Knowledge about a model of scattering/reflection of probe beam, its optics, compensation of a PC beam by FWM, and FWM of scattering/reflection by foam target was obtained. Required injection accuracy of design specifications for a case of introduction of FWM for the Gekko XII laser system at Osaka University was studied.
