Atmospheric CO 2 concentrations are being closely monitored by remote sensing
experiments which rely on knowing line intensities with an uncertainty of 0.5% or better …

We present measurements of approximately 70 isolated, self-broadened, water vapor lines
which are assigned to the (1, 0, 1)–(0, 0, 0),(0, 0, 2)–(0, 0, 0),(1, 2, 0)–(0, 0, 0), and (2, 0, 0) …

Absolute frequencies of unperturbed 12 C 16 O transitions from the near-infrared (3–0) band
were measured with uncertainties five-fold lower than previously available data. The …

We present a cavity ring-down spectrometer which was developed for near-infrared
measurements of laser absorption by atmospheric greenhouse gases. This system has …

We present an experimental study of carbon dioxide absorption in the transparency window
near 700 nm, where different calculations predicted several extremely weak bands. The …

We report a spectrometer employing optically switched dual-wavelength cavity ring-down
spectroscopy (OSDW-CRDS) for high-precision measurements of methane isotope ratios. A …

In micron or nano smart sensing systems, piezoelectric cantilever beams are distributed as
major components in microsensors, actuators, and energy harvesters. This paper …

This paper proposes a novel frequency-shifted interferometry (FSI) fiber cavity ring-down
(CRD) gas sensing with dual-wavelength differential optical absorption that requires no …

Cavity ring-down Faraday rotation spectroscopy (CRD-FRS) is a technique for trace gas
