摘要: 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. report measurements time resolution (<44fs) and spatial profiles (4μm×12μm) apparatus. demonstrate utility this two-color, high-order-harmonic technique by resolving molecular hydrogen elimination C2H4 excited into its absorption band 161nm.
