摘要
A pulsed quantum cascade laser emitting in the wavelength range 9.5 - 9.7 mm at 77.4 K is developed based on the GaAs/Al0.45Ga0.55As heteropair. The laser heterostructure was grown by MOCVD. The threshold current density was 1.8 kA cm(-2). The maximum output power of the laser with dimensions of 30 mu m x 3 mm and with cleaved mirrors exceeded 200 mW.
