Dual‐Comb Spectroscopy With Fully Controlled Repetition Rate and Offset Frequency of Quantum Cascade Laser Frequency Combs

ABSTRACT Quantum cascade laser frequency combs (QCL‐FCs) are promising light sources for sensing applications, thanks to their convenient electrical pumping, chip‐scale footprint, high optical power, and relatively broadband emission in the mid‐infrared molecular fingerprint spec...
