Abstract
Large transparent specimens of polycrystalline zinc oxide with c-axis orientation prepared by the vapor transport method are submitted to open-aperture Z-scan measurement at 532 nm. The effective two-photon absorption coefficient β_<eff> of the polycrystalline ZnO is determined to be 8.6±1.4 cm/GW. Optical power-limiting behavior associated with the two-photon absorption is observed clearly in the polycrystalline ZnO of 0.95 mm thich under the incident beam irradiance of interest.
