High-Resolution Quantum Cascade Laser Dual-Comb Spectroscopy in the Mid-Infrared with Absolute Frequency Referencing
Kenichi N. Komagata, Valentin J. Wittwer, Thomas Südmeyer +2
Quantum cascade laser (QCL) frequency combs have revolutionized mid-infrared (MIR) spectroscopy by their high brightness and fast temporal resolution, and are a promising technolog…
Synchronization of frequency combs by optical injection
Johannes Hillbrand, Mathieu Bertrand, Valentin Wittwer +8
Optical frequency combs based on semiconductor lasers are a promising technology for monolithic integration of dual-comb spectrometers. However, the stabilization of the offset fre…
High-resolution and gapless dual comb spectroscopy with current-tuned quantum cascade lasers
Michele Gianella, Akshay Nataraj, Béla Tuzson +7
We present gapless, high-resolution absorption and dispersion spectra obtained with quantum cascade laser frequency combs covering 55 cm. Using phase-sensitive dual comb des…
