Some recent applications of the free electron laser (CLIO and FELIX) in semiconductor nonlinear optics

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A brief review is given of some recent rf-linac pumped free electron laser experiments. The experiment on two-photon absorption (TPA) in semiconductors was conducted in collaboration with the CLIO group at Orsay. TPA in the narrow gap semiconductors InAs and InSb were measured for the first time over a broad spectral range, from one-photon to two-photon threshold, utilizing the mid-infrared tunability of CLIO. Another experiment on saturation subband spectroscopy in GaAs quantum structures was conducted in collaboration with the Delft and FELIX groups at the FOM-Institute for Plasma Physics Rijnhuizen. FELIX was used to measure the nonlinear intersubband absorption in GaAs/ALGaAs multiple quantum wells.
