Paper Abstract

The nonlinear optical properties of ZnO have been investigated with an excimer pumped ultraviolet dye-laser. The wavelength dependence of the first order diffracted intensity in a self-diffraction experiment has been performed for photon energies below but near the fundamental absorption edge. The measurements indicate a resonant behaviour of the third order nonlinear susceptibility just below the bandgap. Further we have measured the temporal behaviour of the diffracted light. This time dependence indicates that the non-linearity is due to electronic excitations in the crystal.
