The dressed Hamiltonian describing the multiphoton process is presented by means of a canonical transformation.The exact eigenvalues and eigenstates are given for any set of parameters ω_(0),ω and ε.The general evo...
Multiphoton dissociation of C_(4)H_(2)N_(2) molecules at 193nm has been studied at high laser intensities.Emission spectra are recorded from violet(B ^(2)Σ→X ^(2)Σ)bands of CN and the Swan bands of C_(2)(d ^(3)π_(...
