摘要：
This paper presents a model of high harmonic generation which incorporates the internal vibrational degrees of freedom present in molecules. It is shown that vibrational dynamics during the HHG process cause the molecular wavefunction to interfere with itself, in a manner analogous to an optical beamsplitter. In addition, a semiclassical model of the continuum electron is developed which connects with rigorous treatments of electron-ion scattering. (C) 2009 Elsevier B.V. All rights reserved.
