We describe the application of cavity ring-down spectroscopy (CRDS) to the detection of trace levels of ethylene in ambient air in a cold storage room of a fruit packing facility over a several month period. We compare these results with those obtain

In the semiconductor industry, control of ammonia at the parts-per-billion concentration level is critical to insure the integrity of the lithography process. Ammonia is emitted into wafer fab air by various semiconductor processes including CVD, waf

Cavity ring-down spectroscopy (CRDS) can provide high sensitivity, high precision, and absolute calibration in a wide range of environments. We report on a compact cavity ring-down spectrometer that can measure atmospheric toxic industrial compounds

We report on cavity-enhanced second-harmonic generation of 488 nm radiation in a 5 mm long periodically poled KTiOPO4 (PPKTP) crystal pumped by the output of a single-mode 976 nm semiconductor external cavity laser. At a pump laser output power of 66

We report on robustness testing of a highly reliable frequency-doubled, external cavity semiconductor laser (DECSL). The laser module has been demonstrated to survive 6G operating vibration swept from 100 Hz to 500 Hz at 0.25 octaves/min. Impact shoc

It can be quite difficult to probe the harsh and potentially nonequilibrium environment of atmospheric pressure Plasma-Assisted Chemical Vapor Deposition (PACVD) reactors [1]. Sensitive measurement of temperature and trace radical concentrations with
