Abstract

We demonstrate the full frequency stabilization of a Quantum Cascade Laser Frequency Comb by using radio-frequency injection for locking the mode spacing and frequency locking to a crystalline microresonator for stabilizing the offset frequency. A final mode linewidth of 30 kHz over 2 ms is achieved.
