Abstract
We introduce and employ the molecular attoclock method. This allows us to simultaneously trace the nuclear and electron dynamics during H2 fragmentation, and to CEP-control the two-electron emission dynamics on sub-cycle time scales.
Highlights
The laser-sub-cycle mapping between the ionization time of an electron and its final momentum established by the rotations of the electric field vector of circularly or elliptically polarized laser pulses can be exploited for investigating double-ionization dynamics [1,2]
We introduce and employ the molecular attoclock method
The clock needs to be calibrated by the carrierenvelope phase (CEP) of the laser pulses, as has been shown and exploited for measurements on atoms [2]
Summary
The laser-sub-cycle mapping between the ionization time of an electron and its final momentum established by the rotations of the electric field vector of circularly or elliptically polarized laser pulses can be exploited for investigating double-ionization dynamics [1,2]. This allows us to simultaneously trace the nuclear and electron dynamics during H2 fragmentation, and to CEP-control the two-electron emission dynamics on sub-cycle time scales.
