HD+in a short strong laser pulse: Practical consideration of the observability of carrier-envelope phase effects

Abstract

We summarize the results of numerical calculations of ${\mathrm{HD}}^{+}$ in a $7.1\phantom{\rule{0.3em}{0ex}}\mathrm{fs}$ (intensity full width at half maximum) $790\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ laser pulse. The molecule is assumed to be aligned with the linearly polarized laser field and includes two electronic and one nuclear degrees of freedom. We report total dissociation and ionization probabilities from the lowest 10 vibrational states for a range of intensities from ${10}^{13}$ to $7\ifmmode\times\else\texttimes\fi{}{10}^{14}\phantom{\rule{0.3em}{0ex}}\mathrm{W}∕{\mathrm{cm}}^{2}$. The conditions for the observability of carrier-envelope phase (CEP) effects for a mixed initial state and for intensity averaging over the laser focal volume are discussed in detail.
