Article Title: Spectroscopic analysis of breath ethylene and oxidative stress relation with glycaemic status in type 2 diabetes
Article Snippet: The paper presents the CO2 laser absorption spectroscopy (CO2LPAS) techniques as an effective tool for sensitive analysis of ethylene in human breath.. Breath analysis is non-invasive method to monitor the disease states and evolution using biomarkers.. Breath ethylene as a breath biomarker of oxidative stress was determined in the exhaled breath of subjects with type-2 diabetes and a healthy control group using a CO2LPAS system.

Article Title: Non-destructive methods for fruit quality evaluation
Article Snippet: The laser beam is amplitude modulated by a mechanical chopper (DigiRad C-980) working at 564 Hz, focused by a ZnSe lens and introduced in the PA cell.

Article Title: Ammonia Concentration in Ambient Air in a Peri-Urban Area Using a Laser Photoacoustic Spectroscopy Detector.
Article Snippet: By modulating the laser beam with a mechanical chopper model DigiRad C-980 whose operating frequency is the same as that of the PA cell (564 Hz), pressure waves are generated and detected with four sensitive miniature microphones (Knowles electrets EK-303 or EK-23024, sensitivity 20 mV/Pa) mounted in the cell wall.

Article Title: Ammonia Concentration in Ambient Air in a Peri-Urban Area Using a Laser Photoacoustic Spectroscopy Detector
Article Snippet: Before entering the PA cell, the CO 2 -cw laser beam is modulated by a mechanical chopper (DigiRad C-980 and C-995 (30 aperture blade), Terahertz Technologies Inc., Oriskany, NY, USA) that operates at the resonant frequency of the PA cell (564 Hz) and is focused by a ZnSe lens ( f = 400 mm), and introduced in the PA cell where is locally absorbed by IR active molecules.

Article Title: Ammonia and ethylene biomarkers in the respiration of the people with schizophrenia using photoacoustic spectroscopy
Article Snippet: This laser, emitting radiation in the 9.2 to 10.8 μm region on 73 different vibrational-rotational lines, has a maximum power of 6.5 W on the 10P(20) line.23,24,41 Our laser beam was modulated by a high-quality, low-vibration noise and variable-speed (4 to 4000 Hz) mechanical chopper model DigiRad C-980 or C-995 (30 aperture blade), operated at the appropriate resonant frequency of the cell (564 Hz).

Article Title: Experimental Investigation on Water Adsorption Using Laser Photoacoustic Spectroscopy and Numerical Simulations
Article Snippet: The input power of the laser beam was measured with help of a laser radiometer with a measuring head and the optimum laser power is finally adjusted using the screws supporting the optical resonator components.After the input laser power was measured, the light beam of the laser was modulated with a high quality, low vibration noise, and variable speed 4–4000 Hz by a mechanical chopper model DigiRad C-980, Terahertz Technologies Inc., New York, NY, U.S.A., with 30 slot apertures operated at the appropriate resonant frequency of the PA cell (564 Hz).At the point of insertion of the chopper blade, the laser beam diameter is typically 5 mm and is nearly equal to the width of the chopper aperture.
