摘要/Abstract

摘要： This paper reports that a one-colour fs pump--probe measurement has been carried out for studying photoionization/photodissociation of cyclohexanone (C₆H₁₀O) in intense laser field. Two of the fragments from cyclohexanone, C₂H₃⁺ and C₃}H₃⁺, are studied under 800 nm laser pump--probe and the results obtained show similar time evolutions. It proposes a feasible model for analysing the experimental observations of the one-colour {fs} pump--probe measurement. The results demonstrate that as an intermediate product, the excited molecular parent ions play a very important role in photionization/photodissociation processes in intense laser field.
