We investigate nonlinear optics related to the intra-excitonic 1s-2p heavy-hole transition in GaAs/AlGaAs quantum wells. Tuning intense terahertz (THz) light around this resonance we report (i) efficient second order sideband generation and (ii) first clear evidence of the Autler-Townes effect.
Here we first report the first demonstration of passive mode locking in a Ti-sapphire laser end-pumped Tm3+,Ho3+:YAG laser utilizing ISBTs in InGaAs/AlAsSb quantum wells grown on an InP substrate. The experimental setup is schematically shown in Fig. 1. The pump source is a tunable Ti-sapphire laser with a maximum output power of 2.2 W at 785 nm, corresponding to the peak absorption of the Tm3+, Ho3+:YAG...
