The thermal contribution to the nonlinear refractive index of air at 1.064μm was measured with a high-finesse Fabry-Perot cavity and a 500-mW cw laser beam. At room temperature and pressure, the nonlinear refractive-index coefficient of air was found to be n<sub>2</sub><sup>(th)</sup>=(-1.9±0.2)×10 <sup>-14</sup> cm<sup>2</sup>/W for a beam waist radius of 0.23 mm and was found to be independent of the relative humidity. The thermal nonlinearities of N<sub>2</sub> , O<sub>2</sub> , and CO<sub>2</sub> were also measured, and it was found that the dominant contribution to air is its O<sub>2</sub> content.
