Quantum Cascade Random Lasers (QCRLs) feature a broadband gain medium as well as a broadband cavity, which makes them ideal for spectroscopic applications. However, due to mode competition and spatial hole-burning, only discrete modes arise in reality.

The full potential of QCRLs can be reached by perturbing them optically. We present such an optical perturbation scheme, which by the help of deep learning allows for the instantaneous creation of custom emission spectra.
