Abstract

The nonlinear absorptive and refractive dynamics of semiconductor zinc oxide (ZnO) are investigated using a modified time-resolved pump-probe system with phase object performed at 532 nm on picosecond timescale. The measurement method is based on method with a phase object for measurement of optical nonlinearities and standard time-resolved pump-probe system. The sample's nonlinear optical properties can be determined by measuring the normalized transmittance with/without an aperture in the far field. The experimental results show that the nonlinear response of ZnO is a combination of bound-electronic and free-carrier nonlinearities mechanism. With the theory of two-photon induced free-carrier nonlinearity, we fitted the experimental results and the nonlinear parameters of ZnO, such as two-photon absorption coefficient β, two-photon induced free-carrier absorption cross sectionσ and life time of the free-carrier τ_r are obtained.
