Coherent rotational dynamics of molecules in intense laser field

Abstract

Coherent rotational dynamics of gas-phase molecules induced by the excitation with an intense nonresonant ultrafast laser field is discussed. In particular, utilities of quantum-state resolved spectroscopic probe after the nonadiabatic rotational excitation (NAREX) by the ultrafast pulse(s) are described with some examples of double-pulse excitation experiments, which provided detailed information on excitation pathways and realization of full quantum-state reconstruction of a rotational wavepacket. Future prospects of the present method are briefly discussed.
