We report on measurements of the nonlinear index of refraction of air, Nsub2/sub, and Osub2/subat a wavelength close to 10 μm by collinear four-wave mixing of a 200 MW COsub2/sublaser beat-wave. The use of a 200 ps long beat-wave comprising radiation amplified on the 10P20 and 10R16 lines of the COsub2/sublaser provides a sensitive method to measure the small nonlinearities characteristic of the gas phase in a spectral region where no such data exists. |
