Ultrafast electrooptic dual-comb interferometry
Open accessAbstract
Dual-comb interferometry is a particularly compelling technique that relies on the phase coherence of two laser frequency combs for measuring broadband complex spectra. This method is rapidly advancing the field of optical spectroscopy and empowering new applications, from nonlinear microscopy to laser ranging. Up to now, most dual-comb interferometers were based on modelocked lasers, whose repetition rates have restricted the measurement speed to ~kHz. Here we demonstrate a dual-comb interferometer that is based on electrooptic frequency combs and measures consecutive complex spectra at an ultra-high refresh rate of 25 MHz. These results pave the way for novel scientific and metrology applications of frequency comb generators beyond the realm of molecular spectroscopy, where the measurement of ultrabroadband waveforms is of paramount relevance.

By using the intervals and phases of the IFG, the jitters at the entire time window between the triggers can be corrected using software algorithms, as previously studied in dual-comb spectroscopy.
“By using the intervals and phases of the IFG, the jitters at the entire time window between the triggers can be corrected using software algorithms, as previously studied in the scheme of dual-comb spectroscopy [33-36].”
From Jitter correction for asynchronous optical sampling terahertz spectroscopy using free-running pulsed lasers (2023) · cites this paper as [35]
The Dual-comb spectroscopy section (p. 3) describes analyzing interferograms by Fourier transform, but does not describe using their intervals and phases to correct jitter between triggers. Searches for timing and phase correction, jitter between triggers, and software correction found no passage addressing that procedure in our copy. (LLM, conf=0.72)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
