Abstract

From nonlinear transmittance at 532 nm, we have evaluated two photon absorption coefficient and calculated the imaginary part of the third order nonlinear optical susceptibility. The real part describe the nonlinear refractive index change and from degenerate four wave mixing (DFWM) measurements, we obtain the absolute value of the third order nonlinear susceptibility for the investigated ZnSe. Combined with independent measurement of TPA coefficients in this material, this indicates that the measured susceptibility in ZnSe at 532 nm is dominated by nonlinear refraction changes
