Light-Dressed Spectroscopy of Molecules

Research output: Chapter in Book/Report/Conference proceedingChapter


We present a theoretical approach for simulating rovibronic spectra of molecules dressed by medium-intensity laser fields. Numerical results, obtained through the formalism described, are presented for the homonuclear diatomic molecule Na, a system suitable for demonstrating and understanding various aspects of light-dressed spectroscopy. We discuss the physical origin of the peaks in the light-dressed spectrum of Na and investigate the light-dressed spectrum in terms of its dependence on the dressing field’s intensity and wavelength, temperature, and the turn-on time of the dressing field. The possibility of using light-dressed spectroscopy to derive field-free spectroscopic quantities is also addressed.
