Dual-comb quartz-enhanced photoacoustic spectroscopy
Photoacoustic spectroscopy (PAS) using two optical combs is a new-born technique, offering appealing features, including broad optical bandwidths, high resolutions, fast acquisition speeds, and wavelength-independent photoacoustic detection, for chemical

Spectral and temporal characterization of a fused-quartz-microresonator optical frequency comb [PDF]
We report on the fabrication of high-Q, fused-quartz microresonators and the parametric generation of a frequency comb with 36 GHz line spacing using them. We have characterized the intrinsic stability of the comb in both the time and frequency domains to assess its suitability for future precision metrology applications.

Fluid Inclusion Studies of Comb Quartz and Stibnite at the Hishikari Au–Ag Epithermal Deposit, Japan
AbstractFluid inclusion microthermometry was conducted on late‐stage barren comb quartz and the latest stibnite at the Hishikari deposit to characterize the hydrothermal activity responsible for vein formation. Eight fluid inclusion assemblages (i.e.

A 100-KC QUARTZ CRYSTAL COMB REJECTION FILTER
Abstract : A comb filter that provides a high attenuation at each of 63 notch frequencies was designed for a center frequency of 100 kc. Each tooth, or notch, is produced by a quartz crystal operating at series resonance in a bridge circuit, and the shape of the characteristic is typical of a null response.

Accurate frequency referencing for fieldable dual-comb spectroscopy [PDF]
We describe a dual-comb spectrometer that can operate independently of laboratory-based rf and optical frequency references but is nevertheless capable of ultra-high spectral resolution, high SNR, and frequency-accurate spectral measurements.
