Abstract
Four-wave mixing is used to produce a steered optical phase conjugate wave. First and second pump waves are combined with a probe wave in a nonlinear medium within an optical conjugate, producing an optical phase conjugate wave. The magnitude of the wave vectors corresponding to the first and second pump waves are different, causing the optical phase conjugate wave to define a non-zero angle .theta..sub.0 relative to the probe wave. In a first embodiment, the wavelengths of the first and second pump waves are controlled to vary the angle, while in a second embodiment, the intensities of the two pump waves are modified.
