High-Resolution and Gapless Dual Comb Spectroscopy with Current-Tuned Quantum Cascade Lasers
- Conference Paper
We measured gapless, high-resolution absorption spectra spanning 55 cm−1 by simultaneous current-modulation of two quantum cascade laser frequency combs. Detector noise limited spectra were obtained in as little as 10 ms with a resolution of a few MHz.
