Abstract
- We quantitatively investigate the third-order optical nonlinear response of Co-doped ZnO thin films 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<superscript>−5</superscript> cm/W and the third-order nonlinear susceptibility χ<superscript>(3)</superscript> is 2.93 × 10<superscript>−6</superscript> 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 films. [ABSTRACT FROM AUTHOR]
