Potential energy curves for . The ground state is . Up to 3.0 eV, the only two excited states that are coupled to the ground state by transition dipole moment are and .
Photodissociation spectra with a single resonant pump pulse and different peak amplitudes (in ). We use the following keys: Red line with circles, , black line , dotted lines dissociation in , and solid lines, dissociation in . The parameters of the pulse are in the text.
Stark-shifted Franck–Condon thresholds and as a function of the control field amplitude . The arrows indicate the different vertical transitions that can be excited within the envelope of a control pulse with peak amplitude , as explained in Sec. VI.
Population histories of the photodissociation dynamics with (a) the counterintuitive sequence and (b) the intuitive sequence. The parameters of the simulations are given in the text. Black lines are population in , red lines in (the dashed line with circles indicates the dissociation probability ) and blue lines are populations in (the dashed line with squares indicates the dissociation probability ). The inset shows the pulse structure, formed by preceded or followed by .
Snapshots of wave packet dynamics in the photodissociation using (a) the counterintuitive sequence and (b) the intuitive sequence, at different times. The solid lines are the potentials and the dotted lines are the LIPs (when the LIPs are not plotted). The arrow depicts the photon energy chosen in the example. In the first snapshot of the dynamics the wave packets are re-scaled with respect to the following snapshots for better visibility. The parameters of the simulations are given in the text.
Photodissociation spectra in the presence of the control pulse using the counterintuitive sequence with (a) and (b) . The keys of the symbols are the following: Circles are results with peak amplitudes , triangles are results with , and lines with no symbols are results with . The solid line gives dissociation in and the dotted lines dissociation in . The shadowed area gives the population trapped in the bound states of for the case . The pulse parameters are given in the text.
(a) Photodissociation spectra in the presence of the control pulse using the intuitive sequence for different control peak amplitudes and (b) the resulting branching ratio . In (a) we give the total dissociation . The peak amplitude of the control field for the different results is the following: In dashed line ; in black line with squares ; in red line with circles ; in blue line with solid triangles and in blue line with empty triangles . All other parameters in the simulations are given in the text.
