Abstract
We studied the dependence on the dissociative ionization of H2 as a function of carrier-envelope phase (CEP) of few-cycle (6 fs) near-infrared (NIR) laser pulses. For low-energy channels, we present the first experimental observation of CEP dependence for combined dissociation yield (with protons emitted in both directions) and the highest degree of asymmetry reported to date (40%).

[1] More recently, Kremer et al observed a significant (~15%) asymmetry for these low energy channels in H2 [2]. Neither of these studies reported on CEP dependence of the combined dissociation yields including fragments emitted in all directions
