| Abstract: | We show how the single-mode Floquet theory, valid only for sinusoidal field problems, may be generalized to a coupled quasienergy (or dressed-) states formalism, allowing non-perturbative treatment of multiphoton excitation of multilevel quantum systems driven by non-sinusoidal coherent pulse fields. The method is illustrated by a case study of the adiabatic population inversion in a CO Morse oscillator. |
