Gas sensing with a 9 µm thermoelectrically-cooled quasi-cw distributed feedback quantum cascade laser

Not Accessible

Your library or personal account may give you access

Abstract

A compact trace gas sensor based on a thermoelectrically cooled quasi CW quantum cascade laser is reported. Direct absorption of SO2 was used for laser characterization. 2f wavelength modulation spectroscopy was applied to ammonia monitoring.
