1. High Harmonic Generation from solid material (ZnO, Diamond) and metamaterial(metallic nanorod arrays) to produce attosecond laser pulses;
2. Investigation of attosecond laser pulse enhancement induced by localized surface plasmon resonance;
3. Using Pump-probe technic(transient absorption measurement) to characterize the hot electron dynamics in solid materials. The hot electrons are mostly produced by surface plasmon resonance in nanostructures;
4. Attosecond laser pulse measurement and analysis.
