Abstract

When irradiated by an intense pulse of an infrared (IR) laser, molecules emit a coherent radiation composed of a frequency comb of harmonics of the pump laser frequency, ranging from ultraviolet (UV) up to soft X-rays. These harmonics are emitted during extremely short time windows, within the attosecond range. The properties of harmonic emission are of much interest when applied to issues of relevance to AMOP (Atomic, Molecular and Optical Physics) and they have opened a new domain of investigation in the emerging field of attophysics. In the spectral domain, analyzing high harmonic spectra provides original information on the electronic structure of the outer orbitals that are active in the generation process. In the time domain, the use of attosecond pulses of Extreme Ultra-Violet (XUV) harmonics within a pump-probe scheme opens unique opportunities to develop a new time-resolved spectroscopy of transient excited molecular states. In this review, we shall report on recent advances in the field and we shall address several issues of interest with the objective to go beyond the "proof-of-principle" demonstrations that have been reported so far.
