Abstract
We combine different wavelengths from an intense high-order harmonics source with variable delay at the focus of a split-mirror interferometer to conduct pump–probe experiments on gas-phase molecules. We report measurements of the time resolution () and spatial profiles () at the focus of the apparatus. We demonstrate the utility of this two-color, high-order-harmonic technique by time resolving molecular hydrogen elimination from excited into its absorption band at .
