## Abstract We present high power mid‐infrared surface‐emitting single mode GaAs‐based quantum cascade lasers (QCLs). By using an air‐AlGaAs waveguide combined with second‐order distributed feedback processing, we obtained optical output, via the surface, above 3W. Surface‐normal dual‐lobe light em
