英文摘要	To probe ultrafast molecular dynamics, a high spatial-temporal resolution is of crucial importance. Different from the usual pump-probe method, here we present a probing scheme to clock the molecular dynamics with subcycle precision by investigating the correlated electron-nuclear energy spectra in a multicycle laser pulse. The molecular dynamics in the tunneling ionization regime are numerically simulated in a two-dimensional H-2(+) non-Born-Oppenheimer model. It is found that the asymmetry between the yields of electrons ionized in opposite directions along the laser polarization axis shows peaks and valleys alternately as a function of the nuclear energy. Our results show that the temporally resolved asymmetry of the ionization of electrons can be used as a clock to probe the nuclear Coulomb explosion channel with subcycle resolution and extract the corresponding molecular dynamics accurately. This method can be used even when the intensity averaging of the focused laser beam is considered.
