Abstract
An improved method involving three phase conjugates for measuring the phase of complex third-order nonlinear susceptibility ((Chi) (3)) directly has been developed. The principle of this interferometric method is that the phase shift observed on an oscilloscope between two interference signals equals the difference of (Chi) (3)'s phases of two nonlinear media. Therefore, if one of the two media serves as a standard with its known phase of (Chi) (3), the other one's phase can be determined directly. The (Chi) (3)'s phases for some saturable absorption dye-doped polymeric films such as Eosin Y doped in polyvinyl alcohol (Eo/PVA) has been measured at different wavelengths by using this interferometric technique.
