Abstract

A new technique utilizing a broadband incoherent light source and surface second-harmonic generation is proposed for the measurements of the dephasing process of adsorbates. A broadband Fluorescein 548 dye laser having a correlation time of 112 fs was used to measure the dephasing processes of monolayers of rhodamine 6G and retinal molecules adsorbed on glass surfaces. Our experimental data agree with the results of the theoretical analysis based on a resonant three-level model.
