Continuous wave (cw) diode lasers are increasingly being used as light sources in the
visible and near-IR regions of the spectrum for cavity ring-down spectroscopy (CRDS) and …

Much of the important chemistry of the atmosphere takes place on exceedingly small
concentration scales, with principle components occurring at mixing ratios that vary from the …

The paper presents analyses of current research projects connected with explosive material
sensors. Sensors are described assigned to X and γ radiation, optical radiation sensors, as …

A new system for continuous, highly resolved oceanic and atmospheric measurements of N
2 O, CO and CO 2 is described. The system is based upon off-axis integrated cavity output …

An optical analytical instrument based on light emitting diode (LED) incoherent broadband
cavity enhanced absorption spectroscopy (LED-IBBCEAS) was developed for simultaneous …

We have constructed a pulsed cavity ring‐down spectrometer (CARDS) for simultaneous
measurements of nitrogen dioxide (NO2), the nitrate radical (NO3), and dinitrogen pentoxide …

NO 2 concentrations were measured by various instruments during the NO3Comp campaign
at the atmosphere simulation chamber SAPHIR at Forschungszentrum Jülich, Germany, in …

Nitrogen oxides (NO x= NO+ NO 2) are critical intermediates in atmospheric chemistry and
air pollution. NO x levels control the cycling and hence abundance of the primary …

We describe several applications of cavity ring-down spectroscopy (CRDS) for trace matter
detection. NO 2 sensor was constructed in our team using this technique and blue-violet …

A discharge–flow system, coupled to cavity-enhanced absorption spectroscopy (CEAS)
detection systems for NO3 at λ= 662 nm and NO2 at λ= 404 nm, was used to investigate the …
