Abstract	The third-order optical nonlinearity ξ in ZnO microcrystallite thin films from cryogenic to room temperatures using femtosecond degenerate four wave mixing (DFWM) was measured in a forward two-pulse geometry and its magnitude ranges between 10 to 10 esu from 4.2 K to room temperature. The response time of ξ is ultrafast with decay time constant of only 200-300 fs. The microcrystallite ZnO thin films shows a clear exciton absorption peak at approximately 3.325 eV even at room temperature indicating excellent quality of the sample. The peak of DFWM response is also near the exciton peak which clearly shows the enhancement of the optical nonlinearity by exciton.
