Characterization of the optical nonlinearities of ZnSe using Z-scan techniques

We report on the measurements of the nonlinear susceptibility of ZnSe at 783 nm with 110 fs pulses of various intensities. We point out limitations for the measurement of (chi) (5) nonlinear susceptibility using Z- scan technique. We also present a new technique using self- imaging (SIZ-scan) which could provide more sensitive measurements of nonlinear refractive effects.
