Abstract
To achieve a deeper knowledge of the interplay between charge and structural dynamics in molecules, it is necessary to simultaneously probe the dynamics in the molecule on femtosecond and attosecond timescales, on which nuclear motion and charge dynamics occur, respectively. In order to reach these timescales, we take advantage of an extremely non-linear process, high-order harmonic generation (HHG). When an intense infrared (IR) femtosecond laser pulse is focused in a gas, odd harmonics of the driving field are generated, with pulse duration in the femtosecond range for individual harmonics, and attosecond for the light pulses emitted at each half laser cycle.
