The fidelity of phase conjugation by degenerate four-wave mixing in ruby and semiconductor-doped glasses has been measured by means of our own modified Twyman-Green interferometer [Opt. Lett. 14, 183 (1989)] implementing two phase conjugate mirrors. It is shown that the fidelity of phase conjugators with an OG530 color filter as the nonlinear medium reaches a value of 99%. The fidelity of ruby is also reported. Additionally the effect of the recording system on the value of the fidelity is discussed.
