The model presented describes ionization and excitation of nitrogen molecules by a strong and short laser pulse within the same formalism of the density matrix. The dependence of the dipole moment on the vibrational quantum number and a large number of excited levels are taken into account. Populations of the excited levels are significantly influenced by laser intensity, wavelength, polarization, and pulse duration.
We present a model describing ionization and excitation of nitrogen molecules by a strong and short laser pulse. Different from previous publications, both processes are considered within the same formalism of the density matrix. We account for the dependence of the dipole moment on the vibrational quantum number and for a large number of excited levels. Populations of the excited levels depend significantly on the laser intensity, wavelength, polarization, and pulse duration.
