The carrier envelope phase (CEP) dependence in the C-D 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, C2D22+ -> C2D+ and D+, exhibits the CEP dependent asymmetry, while its CEP dependence is out of phase by p with respect to the CEP dependence of the recoil momentum of C2D2+. From a recollisional double ionization model, the asymmetry in the ejection direction of D+ was ascribed to the laser-assisted CAD bond weakening in the few-cycle laser field. (C) 2014 Elsevier B.V.
