摘要：
in this work we demonstrate the use of a stabilized Mid-infrared quantum cascade laser as a local oscillator for ultra sensitive Mid-IR heterodyne detection. We show a measurement of 80dB signal to noise ratio GHz heterodyne signal measured with a resolution bandwidth of 1 Hz using ultrafast quantum well infrared photodetector.
