摘要：

We quantitatively investigate the third-order optical nonlinear response of Co-doped ZnO thin 61 ms prepared by magnetron sputtering using the Z-scan method.The two-photon absorption and optical Kerr effect are revealed to contribute to the third-order nonlinear response of the Co-doped ZnO films.The nonlinear absorption coefficient β is determined to be approximately 8.8 × 10;cm/W and the third-order nonlinear susceptibility x;is 2.93 × 10;esu.The defect-associated energy levels within the band gap are suggested to be responsible for the enhanced nonlinear response observed in Co-doped ZnO 61 ms.
