英文摘要： The photoionization and photodissociation of hydrocarbons and their derivatives is closely related to energy science, environmental science and life sciences, and so it is important and highly challenging to investigate femtosecond laser coherent manipulation on hydrocarbon compounds their derivatives. This project will focus on femtosecond coherent manipulation on the photoionization and photodissociation of hydrocarbons and their derivatives under an intense femtosecond shaping pulses. Based on femtosecond laser precision control technology, ion velocity imaging technology, electron- ion momentum coincidence imaging technology and femtosecond electron diffraction technique, we will study molecular photoionizative and photodissociative dynamic process of hydrocarbon and their derivatives.Based on femtosecond pulse shaping, their ionization dissociation process will be coherently manipulated.Therefore, molecular precision measurement and quantum manipulation have been explored and extended from simple molecule with less atoms to the polyatomic complicated one, from the simple quantum model to the complex quantum one, from weak interaction to the strong complicated one and from few photon nonlinearities to huge photon ones, which provides a theoretical and experimental basis for precision measurement and quantum manipulation of the more complicated bio-molecular system.
