Abstract
We have developed 1.5-mum distributed feedback lasers stabilized on a C2H2 absorption line, which are to be used as the frequency reference in a space Fourier transform interferometer intended for meteorologica l sounding of the atmosphere. The stabilization method is based on the heterodyne spectroscopy technique using a 350-MHz laser diode current modulation. Two 500-cm3 pigtailed stabilized laser modules with 500 m uW of useful power at 1540.7 nm were realized. They show a relative fr equency stability better than 2.10(-10) for observation times between 0.3 and 300 s.
