Abstract

We report a terahertz time-domain spectrometer with more than 6 THz spectral coverage and 1 GHz resolution based on high-speed asynchronous optical sampling. It operates at 2 kHz scan rate without mechanical delay stage. The frequency error of the system at 60 s acquisition time is determined by comparing a measured water vapor absorption spectrum to data reported in the HITRAN database. The mean error of 87 evaluated absorption lines is 142 MHz.

  • Most ASOPS THz-TDS techniques use IFG, sum-frequency generation, or two-photon absorption of pulsed lasers as a trigger for signal accumulation.

    “Most ASOPS THz-TDS techniques use IFG, sum-frequency generation, or twophoton absorption of pulsed lasers as a trigger for signal accumulation [3,11,12,18,31].”

    From Jitter correction for asynchronous optical sampling terahertz spectroscopy using free-running pulsed lasers (2023) · cites this paper as [11]

    The Experimental setup (p. 3) says this ASOPS THz-TDS instrument generates its data-acquisition trigger optically through two-photon absorption. It does not establish that most ASOPS THz-TDS techniques use the listed triggers, or describe IFG or sum-frequency generation as trigger methods. (LLM, conf=0.86)

  • The concept of our method is similar to that of previous studies on frequency stabilization by locking ∆f_r or its harmonics.

    “In this context, the concept of our method is similar to that of previous studies on frequency stabilization by locking ∆𝑓 r or its harmonics [2,11].”

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.
