  • Abstract
    Simultaneous detection of hydrogen sulphide and carbon dioxide by dual wavelength operation of a cascaded strongly gain coupled distributed feedback (DFB) laser in the 1575 to 1585 run region is reported for the first time. By precise dual wavelength tuning of the laser diode both gases were detected using wavelength modulation absorption spectroscopy
