A broadband cavity ringdown spectrometer for in-situ measurements
This paper describes a broadband cavity ringdown spectrometer and its deployment during the 2002 North Atlantic Marine Boundary Layer Experiment (NAMBLEX) to measure ambient concentrations of NO 3 , N 2 O 5 , I 2 and OIO at the Mace Head Atmospheric Research Station, Co. Galway, Ireland. The effective absorption path lengths 5 accessible with the spectrometer generally exceeded 10 km, enabling ...
متن کاملCavity ringdown laser absorption spectra of tungsten oxide
Gas-phase WO was generated by laser vaporization and its electronic spectra investigated by cavity ringdown laser Ž . 16 y1 absorption spectroscopy CRLAS . The tungsten isotopic structure in the W O F–X 0–0 transition at 23405 cm is clearly resolved, and its analysis reveals that the strong interstate interactions previously reported in the matrix are also present in the free molecule in the ga...
متن کاملCavity ringdown strain gauge.
Biconical tapered single-mode fiber, which is common in many telecommunications components, offers an alternative sensor to typical optical fiber strain gauges that are susceptible to temperature and pressure effects and require expensive and sophisticated signal acquisition systems. Cavity ringdown spectroscopy, a technique commonly applied to high-sensitivity chemical analysis, offers detecti...

متن کاملModifications to a Cavity Ringdown Spectrometer to Improve Data Acquisition Rates
Let us know how access to this document benefits you. Abstract Cavity ringdown spectroscopy (CRDS) makes use of light retention in an optical cavity to enhance the sensitivity to absorption or extinction of light from a sample inside the cavity. When light entering the cavity is stopped, the output is an exponential decay with a decay constant that can be used to determine the quantity of the a...
