Cavity ring-down (CRD) spectroscopy is a direct absorption technique, which can be
performed with pulsed or continuous light sources and has a significantly higher sensitivity …

Cavity-enhanced direct frequency comb spectroscopy combines broad spectral bandwidth,
high spectral resolution, precise frequency calibration, and ultrahigh detection sensitivity, all …

The broadband, coherent nature of narrow-linewidth fiber frequency combs is exploited to
measure the full complex spectrum of a molecular gas through multiheterodyne …

We demonstrate highly efficient cavity ringdown spectroscopy in which a broad-bandwidth
optical frequency comb is coherently coupled to a high-finesse optical cavity that acts as the …

Molecular fingerprinting using absorption spectroscopy is a powerful analytical method,
particularly in the infrared, the region of intense spectral signatures. Fourier transform …

A new highly sensitive method for incoherent broad-band cavity-enhanced absorption
