We report the design and performance of terahertz quantum cascade laser sources based on intracavity difference frequency generation in dual-wavelength mid-infrared quantum cascade lasers with a passive nonlinear section at the exit facet, designed for giant second-order nonlinear susceptibility. These devices operate in the mid-infrared at and , with terahertz output at the difference frequency, . Terahertz output of approximately 100 nW was observed up to a heat sink temperature of 210 K.
