We study experimentally the three-body Coulomb explosion dynamics of carbon dioxide dimer
${\rm{(CO_2)}}_{2}^{4+}$ ions produced by intense femtosecond laser field. The three-dimensional momentum vectors as well as kinetic energy are measured for the correlated fragmental ions in a cold-target recoil-ion momentum spectrometer (COLTRIMS). Carbon dioxide dimer is produced during the supersonic expansion of${\rm{(CO_2)_2}}$ gas from a 30 μm nozzle with 10 bar backing pressure. The linearly polarized laser pulses with a pulse duration (full width at half maximum of the peak intensity) of 25 fs, a central wavelength of 790 nm, a repetition rate of 10 kHz, and peak laser intensities on the order of${\rm{8 \times10^{14}}}\;{\rm{W/cm^2}}$ are produced by a femtosecond Ti:sapphire multipass amplification system. We concentrate on the three-particle breakup channel${\rm{(CO_2)_2^{4+}}} \rightarrow {\rm{CO}}_{2}^{2+}+{\rm{CO^+}}+ {\rm{O^+}}$ . The two-particle breakup channels,${\rm{(CO_2)_2^{4+}}} \rightarrow {\rm{CO}}_{2}^{2+}+ {\rm{CO_{2}}^{2+}}$ and${\rm{CO_2^{2+}}\rightarrow CO^++O^+}$ , are selected as well for reference. The fragmental ions are guided by a homogenous electric field of 60 V/cm toward microchannel plates position-sensitive detector. The time of flight (TOF) and position of the fragmental ions are recorded to reconstruct their three-dimensional momenta. By designing some constraints to filter the experimental data, we select the data from different dissociative channels. The results demonstrate that the three-body Coulomb explosion of${\rm{(CO_2)}}_{2}^{4+}$ ions break into${\rm{CO}}_{2}^{2+}+{\rm{CO}}^++{\rm{O}}^+$ through two mechanisms: sequential fragmentation and non-sequential fragmentation, in which the sequential fragmentation channel is dominant. These three fragmental ions are produced almost instantaneously in a single dynamic process for the non-sequential fragmentation channel but stepwise for the sequential fragmentation. In the first step, the weak van der Waals bond breaks,${\rm{(CO_2)}}_{2}^{4+}$ dissociates into two${\rm{CO}}_{2}^{2+}$ ions; and then one of the C=O covalent bonds of${\rm{CO}}_{2}^{2+}$ breaks up, the${\rm{CO}}_{2}^{2+}$ ion breaks into${\rm{CO^+}}$ and${\rm{O^+}}$ . The time interval between the two steps is longer than the rotational period of the intermediate${\rm{CO}}_{2}^{2+}$ ions, which is demonstrated by the circle structure exhibited in the Newton diagram. We find that the sequential fragmentation channel plays a dominant role in the three-body Coulomb explosion of${\rm{(CO_2)}}_{2}^{4+}$ ions in comparison of the event ratio of the two fragmentation channels.-
