Optical phase conjugation by degenerate four‐wave mixing in samples of pristine and iodine‐doped polyphenylacetylene at ruby laser wavelength (694.3 nm) is reported here. The nonresonant values of the third‐order optical susceptibility χ(3) are determined from the measurements of reflectivity of phase conjugate signals.
