Sensitivity of high-order harmonic generation to nuclear motion

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 Schrödinger equation for H 2 + and its isotopic variant D 2 + shows that high-order harmonic gen...

Summary: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 Schrödinger 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.
