A near-infrared tunable diode laser spectrometer called TDLAS has been developed that combines telecommunication-type as well as new-generation antimonide laser diodes to measure C2H2, H2O, CO2 and their isotopologues in the near infrared. This sensor is devoted to the in situ analysis of the soil of the Martian satellite PHOBOS, within the framework of the Russian space mission PHOBOS-GRUNT. In the first part of the paper, we report accurate spectroscopic measurements of C2H2 and (CCH2)-C-13-C-12 near 1.533 mu m, of H2O and CO2 at 2.682 mu m and of the isotopologues (CO2)-C-13-O-16 and (OCO)-O-16-C-12-O-18 near 2.041 mu m and H-2 O-17, H-2 O-18 and HDO near 2.642 mu m. The achieved line strengths are thoroughly compared to data from molecular databases or from former experimental determinations. In the second part of the paper, we describe the TDLAS spectrometer for the PHOBOS-GRUNT mission.
