Terahertz Difference Frequency Generation in Quantum Cascade Lasers Conference Paper uri icon


  • We demonstrate intra-cavity terahertz difference-frequency generation in quantum cascade lasers. A two-wavelength quantum cascade laser with monolithically integrated optical nonlinearity emitting at 7.6 and 8.7 μm was used to generate difference frequency at 62 μm. © 2007 Optical Society of America.
