Application of phase conjugate optics to optical systems
 A phase conjugate light generation apparatus for various optical systems, wherein pump light and input signal light are supplied to a non-linear optical medium to generate output signal light and phase conjugate light within the non-linear optical medium. The output signal light and the phase conjugate light are extracted by a signal light/phase conjugate light extraction unit and outputted from respective output ports.
