英文摘要: A new CPA femtosecond laser system was built up. The output of the system is centered at 808 nm with 8 mJ/pulse power and 60 fs pulse width at 20 Hz repetition rate. In this paper 9 we present the detail description of this femtosecond laser system and our initial experimental investigation of de-excited dynamics of 1,3-dichrolobenzene in its S, excited state with the laser system 9 combined with the time-flight mass spectrometer, pump-probe technique and, supersonic molecular beam. Quantum beat phenomenon of 1,3-dichrolobenzehe in its S, excited state was clearly observed for the first time in real time scale. The lifetime constant and the quantum beat frequency of Si excited state were obtained. The photodissociation process of 1,3-dichlorobenzene is illuminated.
