摘要：
A unipolar quantum cascade laser operating at 9.7 mu m and a temperature of 77K based on the AlGaAs material system is reported. Collected peak output powers > 1W 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 240mW/A.
