Detector non-linearity is an important factor limiting the maximal power and hence the signal-to-noise ratio (SNR) in dual-comb interferometry. To increase the SNR without overwhelming averaging time, photodetector non-linearity must be properly hand

Photodetector nonlinearity, the main limiting factor in terms of optical power in the detection chain, is corrected to improve the signal-to-noise ratio of a short-time measurement in dual-comb spectroscopy. An iterative correction algorithm minimizi

We add optical referencing to a technique interrogating gas samples with two frequency combs by varying their repetition rate difference periodically. The reduce interferogram measurement time yields an improved SNR and an optimized resolution.

A method to measure and correct for spectral baseline fluctuations in dual-comb interferometry is presented. Fluctuations can be measured from the amplitude of beat notes between combs and a continuous wave laser or from a separate measurement of the

The impact of photodetector nonlinearity on dual-comb spectrometers is described and compared to that of Michelson-based Fourier transform spectrometers (FTS). The optical sampling occurring in the dual-comb approach, being the key difference with FT

The phase information provided by the beat note between frequency combs and two continuous-wave lasers is used to extrapolate the phase evolution of comb modes found in a spectral region obtained via nonlinear broadening. This thereafter enables usin

We frequency locked a commercial ITLA (integrable-tunable-laser-assembly) laser to an optical frequency comb with arbitrary carrier frequency within the telecom L band (1570-1625 nm). We achieved long-term (days) frequency stability below ±1.5 Hz.

Nonlinearity of a commercial balanced photodetector is explained and corrected for dual-comb interferograms to yield high signal-to-noise ratio for short time measurements even in the case of a fully saturated detector.
