Abstract

The resonant nonlinear refractive indices of important IR-active, minor air constituents at mid-IR and long-wave IR wavelengths were measured using a Mach–Zehnder interferometer. Measurements in H₂O vapor were performed near 2.94, 9.3, and 10.2 µm wavelengths, and measurements in CO₂ and CO gas were performed near 9.3 µm. These measurements suggest that the nonlinearity of air can be greatly increased for relatively narrowband mid-IR and long-wave IR laser pulses.
