Revealing the dissociation channels of mixed photons for H2+ in bicircularly polarized laser pulses

Abstract We theoretically study the dissociation of H 2 + driven by the bicircularly polarized (BiCP) laser pulses. It is shown that there is a possibility for the molecule dissociating through the mixed-photon channels, in which the system simultaneously absorbs multiple photons of different freque...

Summary:Abstract We theoretically study the dissociation of H 2 + driven by the bicircularly polarized (BiCP) laser pulses. It is shown that there is a possibility for the molecule dissociating through the mixed-photon channels, in which the system simultaneously absorbs multiple photons of different frequencies from the BiCP pulses. Setting the frequency ratios of 1:2 and 1:3 for the BiCP pulses reveals the mixed-photon dissociation channels from the interference patterns in the angle-resolved kinetic energy spectra. In addition, by applying the wave packet interference approach, we show that one can further estimate the fragment yield ratios between different dissociation channels that lead to the same kinetic energy.
