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 H 2 O vapor were performed near 2.94, 9.3, and 10.2

Lasing is studied in CO2 pumped at ~4.3 µm by a tunable Fe:ZnSe laser. Gain is measured at ~10 µm at pressures ≤12 atm where gain bandwidth is broad enough for potential picosecond pulse amplification.

We report interferometric measurements of the resonant nonlinearity of CO and CO2 gas using a continuously tunable, multiatmosphere CO2 laser. The implications of these measurements to atmospheric nonlinear optics will be discussed.

Time- and frequency-resolved measurements of resonant nonlinear refraction of mid-IR radiation by CO and CO2 gas reveal a fast optical nonlinearity that is dominated by powerbroadening resulting in sign reversals of the nonlinear refractive index.

Gain dynamics in a 10 pm CO2 amplifier pumped by a 4.3 pm Fe:ZnSe laser are studied. Measured gain coefficients reached 30%/cm, indicating potentially high efficiency for short pulse amplification.

We present time- and frequency-resolved measurements of self-focusing and self-defocusing of 4.3–4.8 μm Fe:ZnSe laser pulses tuned near rovibrational transitions of CO 2 And CO. We estimate the resonant nonlinearity of the air at 4.3 μm and discu

We use time- and frequency-resolved measurements of self-focusing and self-defocusing of 4.3-\ensuremath{\mu}m radiation in ${\mathrm{CO}}_{2}$ gas to study the resonant nonlinear optical response in the vicinity of individual rovibrational lines. Me
