    A Tuneable near to mid-infrared pump, terahertz (THz) probe spectroscopy in reflection geometry has been constructed in Professor Nan-Lin Wang’s laboratory, International Center for Quantum Materials, Peking University. The setup is capable of exciting the bulk materials with pump pulses ranging from 1.2 μm to 15 μm (shown in color yellow), and detecting the transient photoinduced subtle changes of reflected electric field at the frequency of 0.25-2.5 THz [Detail] ...
