Research Field

1. Molecular Image

Generally, the molecular structure is imprinted in the laser induced ionization or high harmonic generation. A new molecular imaging method is developed based on this idea recently. We are going to solve the challenging problem in such an open model.

2. Quantum Coherent Control of The Chemical Reaction

Controlling the chemical reaction is one of the exciting goals of the photochemistry and attosecond physics. The channel of the chemical reaction is due to the ultrafast movement of the electron inside the molecule. The up-to-date laser technology is able to steer the electron movement in the attosecond time scale. We collaborate with the experimental and theoretical groups in US, Germany and Australia to discover new control strategies.

3. Creation of The New Light Source

The interaction of Ti-Sapphire or mid-infrared laser pulse with molecules and atoms may radiate the XUV or THz pulse. Currently, THz is widely used in military, commerce. The ultrashort XUV pulse is the fastest camera in the world, which is used to capture the ultrafast process. We are going to find new strategies to create new light sources.

4.  Pair-creation in extremely strong laser fields

By numerically solving the time-dependent Dirac equation, we study the pair-creation with extremely strong laser fields. We are excited to observe the ultrafast transition between energies and matters.
