Study on multiphoton processes in intense laser fields using the quadratic anharmonic Lie algebraic hamiltonian of diatomic molecule

摘要

The quadratic anharmonic Lie algebraic hamiltonian of a non-rotation Mores oscillator is used to study the multiphoton processes of diatomic molecule placed in intense laser fields. The averaged absorb energy spectra of multiphoton transition are calculated. The long-time behaviors and the effect of laser phase in multiphoton process also are investigated.
