Abstract :
The carrier envelope phase (CEP) dependence in the CD bond breaking of C2D2 induced by an intense few-cycle laser pulse is investigated. The ejection direction of D+ ions generated from the Coulomb explosion, C 2 D 2 2 + → C 2 D + and D+, exhibits the CEP dependent asymmetry, while its CEP dependence is out of phase by π with respect to the CEP dependence of the recoil momentum of C 2 D 2 + . From a recollisional double ionization model, the asymmetry in the ejection direction of D+ was ascribed to the laser-assisted CD bond weakening in the few-cycle laser field.
