Fragmentation of CD$^{+}$ induced by intense ultrashort laser pulses

ORAL

Abstract

The fragmentation of CD$^{+}$ in intense ultrashort laser pulses was investigated using a coincidence three-dimensional momentum imaging technique improved by employing both transverse and longitudinal electric fields. The most probable dissociation pathways for the two lowest dissociation limits, C$^{+} + $ D and C $+$ D$^{+}$, were identified for 22 fs, 798 nm and 50 fs, 392 nm pulses. Curiously, the charge-asymmetric dissociation of CD$^{2+}$, which was measured using 798 nm photons, was not observed with 392 nm photons at the same peak intensity.
