摘要：

The harmonic generations of molecular ion H-2(+) and D-2(+) exposed to an intense laser field have been studied with the collinear reduced-dimensionality model. The numerical solution of the time-dependent Schrodinger equation for H-2(+) and its isotopic variant D-2(+) shows that high-order harmonic generation is sensitive to the initial vibrational states of the molecular ion. By comparing the spectra of H-2(+) with D-2(+), it is shown more intense harmonics are generated in lighter isotopes. (C) 2010 Elsevier B.V. All rights reserved.
