With a multi-cycle driving laser, the produced high harmonics are a train of attosecond pulses in time domain.
We plan to generate very intense attosecond pulse trains (APTs) and use these APTs to study nonlinear response of atoms,
molecules and material in attosecond domain. A high repetition rate (1 khz), high pulse energy (20mJ/pulse) ultrafast laser system
will be used to produce micro-joule harmonics in EUV regime. The system of interest include correlated double ionization, charge transfer
in polyatomics and photoionization induced electron relaxation.
