✦ Synopsis

We report the first theoretical study of the structure of laser-induced vibrational quasi-energy (VQE) resonance states of D: 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 electronicfield potential surface and the multiphoton dissociation rates can be modified significantly, suggesting some degree of 'coherent control' of multiphoton dynamics may be feasible.
