Use of an intense microwave laser to dissociate a diatomic molecule: Theoretical prediction of dissociation dynamics#

摘要

By employing an intense microwave laser of wavelength 116.65 μm with intensities 1 × 1013 and 5 × 1018 W cm − 2, respectively, the conclusion is reached theoretically and computationally that it is possible to dissociate the CO molecule, modelled as a Morse oscillator. It is predicted that for above-threshold dissociation (ATD), the molecule should absorb 1044 photons of the given wavelength in order to reach the lowest edge of the vibrational continuum. A consistent analysis of the predicted dissociation process is provided though the time-dependent probability density, dissociation probability, norm, potential function, HHG and ATD spectra, obtained by numerically solving the time-dependent vibrational Schödinger equation.
