Quasi-continuous-wave operation of AlGaAs/GaAs quantum cascade lasers

, 2005
Quasi-continuous-wave operation of AlGaAs/GaAs-based quantum cascade lasers (lambda similar to 9 mu m) up to 165 K is reported. The strong temperature dependence of the threshold current density and its higher value in high duty cycle is investigated in ...
