  • Abstract
    A unipolar quantum cascade laser operating at 9.7 μm and a temperature of 77 K based on the AlGaAs material system is reported. Collected peak output powers >1 W per facet are demonstrated, which it is believed have never been achieved before for quantum cascade lasers emitting at this wavelength. The maximum slope efficiency is 240 mW/A
