Abstract

In the present paper a high-resolution spectroscopic method, that allows obtaining single shot spectra of Raman-active molecular transitions in non-stationary media with a resolution of ~0.1 cm-1, was developed. The method is based on application of a Fabry-Perot interferometer to spectral analysis of CARS signal from Raman transition with further detection of an interference pattern by a two-dimensional photo-matrix. The implementation of Dual-broadband (DBB) CARS configuration for effective spectral averaging over pump and Stokes lasers spectra together with angular averaging of CARS intensities along complete circumference of Fabry-Perot interference patterns leads to significant improvement of interferogram quality, so that nearly all of the single shot interference patterns obtained for Q-branch lines of hydrogen molecule in a gas probe volume became suitable for linewidth measurements.
