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


Ultrafast mid-infrared pump-probe experiments are used to study gain dynamics and transport processes in quantum cascade lasers below and above threshold. We observe for the first time how stimulated emission drives the current through the cascade heterostructure.
