Gapless High-Resolution Dual Comb Spectroscopy with Current-Tuned Quantum Cascade Lasers

Not Accessible

Your library or personal account may give you access

Abstract

We measured gapless, high-resolution absorption spectra spanning 55Hz 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.
