    "abstract": "In present paper we develop an analytic theory for the harmonic generation of\nsymmetric diatomic molecular ions beyond two-level model, emphasizing the\ninfluence of charge-resonance (CR) states those are strongly coupled to\nelectromagnetic fields for large internuclear distance. With taking into\naccount the continuum states that is ignored in the two-level model and become\nimportant for intense laser case, our model is capable to produce spectrum for\nthe whole range of harmonic orders consisting of a molecular plateau due to the\nCR transition and an atomic-like plateau for a long-wavelength excitation, and\nin good agreement with numerical results from directly solution of the\nSchr\\\"odinger equation. Our theory also identifies the crucial role of the CR\nstates in the fine structure of harmonic spectrum and shows that the harmonic\ngeneration in molecular system can be effectively controlled by adjusting the\ninternuclear distance.",
