摘要: We have constructed a new interferometer that uses two phase-conjugate mirrors. This device allows for the measurement of relative phase shift and ratio nonlinear susceptibilities materials. been able to measure weak reflectivity signals not detectable by normal degenerate four-wave mixing methods. It has determined χ(3) value colloid semiconductor glass OG530 at 532 nm is 7 × 10−12 esu.
