Time-resolved semiconductor spectroscopy in the mid-infrared and Terahertz regimes

This talk will focus on several research topics exploiting our free-electron (FEL) and modelocked Ti:Sapphire lasers to investigate semiconductor nanostructures. Pump-probe spectroscopy and two-photon detection is used for time-resolved investigations of intersubband transitions in semiconductor quantum wells and for FEL pulse diagnostics, respectively. Terahertz emitters based on interdigitated metal stripe arrays will also be discussed.
