We experimentally demonstrate the Coulomb explosion process of CS_2 molecule under a near-infrared(800 nm)intense femtosecond laser field by a DC-sliced ion imaging technique. We obtain the DC-sliced images of these fragment ions S~+, S~(2+), CS~+, and CS~(2+)by breaking one C–S bond, and assign their Coulomb explosion channels by considering their kinetic energy release and angular distribution. We also numerically simulate the dissociation dynamics of parent ions CS_2~(k+)(k = 2–4) by a Coulomb potential approximation, and obtain the time evolution of Coulomb energy and kinetic energy release, which indicates that the dissociation time of parent ions CS_2~(k+) decreases with the increase of the charge number k.These experimental and theoretical results can serve as a useful benchmark for those researchers who work in the related area.
We experimentally demonstrated the Coulomb explosion process of CS_2 molecules under a near-infrared (800 nm) intense femtosecond laser field by a DC-sliced ion imaging technique. We obtained the DC-sliced images of these fragment ions S ~ +, S ~ 2+, CS ~ +, and CS ~ (2+) by breaking one C-S bond, and assign their Coulomb explosion channels by considering their kinetic energy release and angular distribution. We also numerically simulate the dissociation dynamics of parent ions CS_2 ~ (k +) (k = 2-4) by a Coulomb potential approximation, and obtain the time evolution of Coulomb energy and kinetic energy release, which indicates that the dissociation time of parent ions CS_2 ~ (k +) decreases with the increase of the charge number k.These experimental and theoretical results can serve as a useful benchmark for those research who work in the related area.
