Abstract
We have developed a new method to measure molecular rotational temperature in a supersonic gas beam, using nonresonant pump and probe femtosecond laser pulses, where the pump forms a rotational wave packet of molecules, and the probe produces high-harmonic radiation from coherently rotating molecules. The rotational temperature can accurately be derived with high spatial and temporal resolutions from the Fourier spectrum of time-dependent harmonic signals. The validity of this method was demonstrated for an expanding supersonic flow of N2 beam with a rapid temperature decrease.

In producing the frequency spectrum of the observed time-dependent signal, we ignore the initial rapid change at Δt ≈ 0 that is induced by the high intensity of superimposed pump and probe pulses [8].
