Light-induced thermoelastic spectroscopy (LITES) is a promising optical approach for gas
sensing, which uses a quartz tuning fork (QTF) as a photothermal detector, instead of a …

Cavity ring-down spectroscopy (CRDS), first pioneered in 1988 by O'Keefe and Deacon, 1
has evolved into a newgeneration, precision spectroscopy in recent years and subsequently …

Nonlinear tomography can be combined with line-of-sight measurement techniques and
take the full advantage of the nonlinear relationship between the target fields to be …

Shot-noise-limited Doppler-broadened (Db) noise-immune cavity-enhanced optical
heterodyne molecular spectrometry (NICE-OHMS) has been realized by implementation of …

The detection sensitivity of noise-immune cavity-enhanced optical heterodyne molecular
spectroscopy (NICE-OHMS) is often limited by background signals that bring in drifts. A …

A novel, to the best of our knowledge, noise-immune cavity-enhanced optical heterodyne
molecular spectrometry (NICE-OHMS) has been developed, utilizing optical feedback for …

The response of an optical cavity to incomplete extinction of nearly resonant incident light
was experimentally examined. Measurements were performed using a Pound-Drever-Hall …

To expand the applicability of noise-immune cavity-enhanced optical heterodyne molecular
spectrometer (NICE-OHMS), a universal system incorporating a fiber-coupled single …

Lidar is an effective tool for high-altitude atmospheric measurement in which a weak
absorption line for the target gas is selected to ensure a large optical depth. The laser …

We design and construct a resonant photodetector (RPD) with a Q factor of 320.83 at the
resonant frequency of 38.5 MHz on the basis of a theoretical analysis. Compared with the …
