Attosecond Molecular Science
The control of the electric field waveform of laser light E(t)=E0(t)cos(ωt+ɸ), with envelope E0(t), frequency ω, by the carrier envelope phase (CEP) ɸ opened the door for the direct manipulation of electron dynamics in atomic and molecular systems. For frequencies in the range of visible light this waveform changes on an attosecond timescale. Waveform controlled few-cycle pulses have been used to control electron localization in the dissociative ionization of the prototype molecules D2 and HD. These experiments will be introduced together with recent efforts to resolve the electron localization dynamics on attosecond timescales. New results on the phase dependent ionization, dynamic orientation and dissociation of a multi-electron molecule, carbon monoxide (CO), give evidence that the steering of electrons is not limited to single-electron systems and that the future of attosecond molecular science is bright.
