Adaptive control of quantum cascade random lasers

Together with the THz lab at TU Wien we show in a new Nature Communication that quantum cascade random lasers can be adaptively controlled by a suitably shaped infrared beam. Following a control strategy developed by Nicolas Bachelard, an initially multi-mode THz random laser is turned into a tunable single-mode source. Discussions of our work can be found at the Austrian Press Agency, Chemie.de and at Analytica News.
