Abstract

In this study, measurements of the NO A ²Σ⁺ n′ = 2 → X ²Π_r n″ = O fluorescence yield were carried out as a function of incident laser intensity. It was found that light at wavelengths to the blue of the A ²Σ⁺ n′ = 2 ← X ²Π_r n″ = O two-photon absorption resonance in the low-field limit result in population of the n′ = 2 vibrational level at intensities >2×10 W cm². A kinetic model predicted that the variation of the A ²Σ → X ²Π_r fluorescence allows a quantitative estimate of the extent of the ac Stark shift of the 3 so A ²Σ⁺ electron as at least 0.4 of the full ponderomotive shift expected for a free electron.
