title: Test of fidelity of phase conjugation.
abstract: The fidelity of the phase-conjugate signal produced by degenerate four-wave mixing was evaluated by conjugating and recombining the multiple-beam output from a phase grating. A single output beam resulted. If one or more of the beams emerging from the grating were blocked, additional beams appeared whose relative amplitudes agreed with theory for a perfect phase conjugator.
