TITLE: Manipulation of ultrafast electron dynamics in autoionizing systems with attosecond light pulses
 ABSTRACT:
In our theoretical study, we propagate an attosecond light pulse and a time-delayed intense laser in the pump-probe scheme through an autoionizing atomic gas medium, where the controlling factors\such as the laser intensity and the time delay\are crucial quantitatively in resolving the dynamics of the system. The measurability of the results is also discussed. The study demonstrates a high degree of control of the light-matter interaction in the attosecond timescale.

TITLE: Attosecond Dynamics of Inner-Shell Ionization of an Excited Helium Atom
ABSTRACT:
We present time-resolved ab-initio study of the attosecond dynamics of electron-electron correlation during single-electron, single-photon ionization of an excited helium atom. We identify multiple time-scales, caused by the interplay of the initial shake-up excitation with the excitation cascades, which we call knock-up, induced by the post-ionization interaction of the outgoing core electron with the electron residing in the outer orbit.

TITLE: High Harmonic Generation in the Water Window using intense sub-two-cycle IR pulses
ABSTRACT:
We present the current status of our intense IR laser source and its application to high harmonic generation in the water window.  The light source is based on optical parametric chirped pulse amplifiers using BIBO crystals. We obtained the output of 9.0 fs, 0.55 mJ around 1.6 um at 1 kHz.  The carrier-envelope phase (CEP) is also passively stabilized.  We observed high harmonics up to 300 eV with clear CEP dependance.

TITLE: High-order harmonic generation spectroscopy of static and dynamic polyatomic molecules
ABSTRACT:
In recent years high-order harmonics generated (HHG) by intense infrared and mid-infrared lasers have been shown to be able to reveal the target structure information. We consider HHG for polyatomic molecules, under the condition that the interatomic separations are fixed or undergoing large displacements. Based on the quantitative rescattering theory and include medium propagation effects, we demonstrated the success and the limitations of using HHG as a tool for probing the structure of larger molecules.
