Room temperature terahertz quantum cascade laser source based on intracavity difference-frequency generation Academic Article uri icon

abstract

  • We report on our progress in the development of a terahertz quantum cascade laser source based on intracavity terahertz difference-frequency mixing in a dual-wavelength mid-infrared quantum cascade laser with the active region engineered to possess giant second-order nonlinear susceptibility. In this letter, we demonstrate devices that operate in mid-infrared at 1 =8.9 m and 2 =10.5 m and produce terahertz output at 60 m via difference-frequency generation with 7 W output power at 80 K, 1 W output at 250 K, and still approximately 300 nW output at 300 K. 2008 American Institute of Physics.
