A λ≃9.7 µm GaAs/Al0.45Ga0.55As quantum cascade laser with an In0.47Al0.53P waveguide is reported that demonstrates record low threshold current densities for the GaAs/AlxGa1-xAs materials system in the mid-infrared. Under pulsed operation, threshold current densities of 2.2 and 4.4 kA/cm2are observed at 240 and 300 K, respectively, and laser emission is maintained up to temperatures of at least 330 K. The laser was grown by metal-organic vapour phase epitaxy, and emits peak optical powers of up to 0.57 W at 240 K and 0.16 W at 300 K.
