Abstract :
In the present work, we demonstrate the feasibility of hydrogen sulfide (H2S) trace detection by means of off-axis integrated cavity output spectroscopy (OA-ICOS) using a DFB diode laser at ~ 1571.8 nm. A minimum detectable H2S concentration of 700 ppb (signal-to-noise ratio, SNR=3) was achieved.
