The article describes an application of cavity enhanced absorption spectroscopy for nitric oxide and nitrous oxide detection. Both oxides are important greenhouse gases that are of large influence on environment, living organisms and human health. These compounds are also biomarkers of some human diseases. They determine the level of acid rain, and can be used for characterization of specific explosive materials. Therefore the sensitive detectors of these gases are of great importance for many applications: from routine air monitoring in industrial and intensive traffic areas, to detection of explosives in airports, finally for medicine investigation, for health care, etc. Our compact detection system provides opportunity for simultaneous measure of both NO and N2O concentration at ppb level. Its sensitivity is comparable with sensitivities of instruments based on other methods, e.g. gas chromatography or mass spectrometry.
