In our contribution we investigate nonlinear optics related to the hydrogen-like intraexciton 1s-2p heavy-hole (hh) transition in GaAs/AlGaAs quantum wells. Tuning intense terahertz (THz) light of the Dresden free-electron laser around this resonance we report (i) efficient sideband generation and (ii) clear evidence of the Autler-Townes effect.

Keywords: free-electron laser; sideband generation; Autler-Townes; AC Stark
