Abstract

Self-pumped optical phase conjugation, in which a single incident laser beam generates its phase conjugated, replica via some optical wave mixing effect in a nonlinear optical material, is a fundamentally interesting and practically useful process. Usually, the signal originates as some coherently scattered noise from the pump laser beam, e.g., owing to scatterers in a crystal, spontaneous Brillouin scattering, etc.
