Attosecond Pulse generation
A ultrabroad discrete or supercontinuum XUV spectrum can be generated via the protocol of high-harmonic generation to serve as a table-top attoXUV or even soft X-ray light source via further pulse compression in time-domain.

Attosecond Molecular Spectroscopy
A molecular-frame angular resolved asymmetric photoelectron emission time delay is observed in the vicinity of the Shape Resonance of the diatomic molecule and polyatomic molecule.

Attosecond Cluster Spectroscopy
A size-resolved photoelectron emission time delay is observed in water clusters which is atributed to the role of electron localization and delocalization as a function of molecular symmetry.
