Abstrakt:	Abstract: Lasing in MBE-grown impulsively pumped quantum cascade lasers of 9.6 μm at 140 K has been demonstrated. The active area is based on three-phonon resonance scattering of electrons. An In0.53Ga0.47As/Al0.48In0.52As solid alloy heteropair was used to form periods of quantum cascade lasers. The upper In0.52Al0.48As cladding of the waveguide was made thick. Alloyed and unalloyed lower metallization systems were studied. The threshold current density for a ridge laser 1 mm long and 27 μm wide has been found to roughly equal 3 kA/cm2 at 87 K. The optical output power has been estimated at a level of 20-35 mW. [ABSTRACT FROM AUTHOR]
