Abstract
We report the first theoretical study of the structure of laser-induced vibrational quasi-energy (VQE) resonance states of D+2 in intense one- and two-color (fundamental and its third harmonic) laser fields by means of the complex-scaling generalized Fourier-grid Floquet Hamiltonian technique. Stabilization and chemical bond hardening for high-lying VQE resonances are observed. It is shown that by tuning the relative phase between the fundamental and the third harmonic fields, the electronic-field potential surface and the multiphoton dissociation rates can be modified significantly, suggesting some degree of 'coherent control' of multiphoton dynamics may be feasible. © 1994.
