Ti:Sapphire Oscillators
We have two home-built Ti:Sapphire Oscillators that delivers 10fs laser pulse at 70/80MHz, single pulse energy >13nJ@800nm, and >2nJ@400nm by frequency doubling. See the schematic drawing here.
Time-Resolved Two-Photon-Photoemission Spectroscopy
We built a Time-Resolved Two-Photon-Photoemission Spectroscopy system (TR-2PPE)under low temperature and ultrahigh vacumm to study the carrier excitation and relaxation processes in solid-state materials. See the schematic drawing here
Time-Resolved Photo Emission Electron Microscopy
We have Interferometric Time-Resolved Photo Emission Electron Microscopy (ITR-PEEM) for surface plasmon experiments. See the schematic drawing here.
Pump-Probe Reflective Electro-Optical Sampling
We study ultrafast carrier and phonon dynamics in semiconductors by Pump-Probe Optical-Electro Sampling technique. See the schematic drawing here.
