Harmonic generation and multiphoton ionization near an autoionizing resonance
作者： G. Alber , P. Zoller

摘要: We theoretically study intensity-saturation effects in resonant harmonic generation and multiphoton ionization. A first laser excites a two-photon resonance which is coupled by second to an autoionizing state. Starting from effective Hamiltonian for the three atomic states, we derive set of equations density matrix gaseous medium electromagnetic field within semiclassical framework. present discuss analytical numerical solutions these show variety line profiles depending critically on intensities incident pulses.
