Triatomic molecular ionization and dissociation in strong laser fields

We extend molecular ionization and dissociation studies in strong laser fields from diatomic molecules to triatomic molecules. In this work, we study two dissociation pathways in double ionized triatomic molecule, CO$_{2}$, one two-body dissociation channel, CO$^{+}$+O$^{+}$, and the other three-body dissociation channel, C + 2O$^{+}$. The two-body dissociation channel shows a stronger nonsequential rate than the three-body dissociation channel. We found that electronic structure plays a key role on the dissociation process, in consistent with our previously established work in diatomic molecules.
