Abstract

Desorption of molecularly adsorbed O2 from Pt(111) by 620 nm femtosecond laser pulses shows a nonlinear fluence dependence of the yield and a subpicosecond response time. The measurements were carried out by means of a two-pulse correlation scheme using a pulse counting quadrupole mass spectrometer. These results can be understood with a model involving multiple reexcitations of the adsorbate by photogenerated carriers.
