Abstract

We study theoretically the detachment of H⁻ by a linearly polarized few-cycle laser pulse. We show that the angularly resolved distribution of the electrons is very sensitive to the carrier envelope phase (CEP) and the duration of the short laser pulse. This in turn provides an additional means to measure the CEP of a laser pulse at lower laser intensities.
