Abstract

A DFB semiconductor diode laser spectrometer operating between 1 micrometers and 2 micrometers has been developed. High sensitivity detection measurements are carried on with different schemes, from pure linear absorption to two-tone frequency modulation. Results, including collisional lineshape parameters, are reported for various molecules of medical and environmental interest such as CO, CO₂, H₂S, NH₃ and O₂.
