Abstract
A quantum cascade laser emitting in the spectral range of 9.7 μm at 77 K has been developed. The laser heterostructure based on GaAs/AlGaAs was grown by the MOCVD technology. In the pulsed operation mode, the threshold current density of ∼2 kA/cm 2 and the emission power of above 200 mW have been obtained for the laser of the dimensions of 30 μm × 3 mm.
