摘要
In this work we explore the high-order harmonic generation in the H-2(+) molecule under the action of phase shaped pulses. To this end, quantum mechanical wavepacket calculations are performed within a collinear model of H-2(+). We analyze the effect of a chirp to the plateau extension of the HHG spectrum, observing significant differences with respect to the sign of the chirp parameter. This result is found to originate from a subtle electron recollision dynamics within the chirped laser pulses, as substantiated by classsical trajectory calculations. Extension of this work focuses on including the nuclear motion of H-2(+).
