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. More

Atomic Photoionization time delay

A Freenman Resonance photoionization time delay (120as between 4f/5p in argon atoms) and atomic partial wave meter protocol was established in atomic photoionization physics.

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. More

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. More
