Research Abstract

Following the recent developments in laser technology, ultrashort xuv(extreme ultraviolet) light pulses with duration of several hundred attoseconds have been reported. Such pulse durations are comparable to the time scale of the electronic motion in atoms and molecules, thus opening up a route to the time-resolved study of electron dynamics in matter. In this work, we studied real time analysis of correlated multiply excited states of atoms using such ultrashort laser pulses and related atomic and molecular dynamics under intense laser fields.
