Abstract
12 IASI is a key instrument of the payload on METOP, a European meteorological platform. METOP will provide meteorology with atmosphere emission spectra, allowing to set atmosphere temperature and moisture profiles with high accuracy. In order to achieve these specifications, several new and innovative technologies and technical answers have had to be developed. Among them, the reference laser of IASI presents challenging concepts and widely uses the last commercial developments of telecommunication technologies. The reference laser is frequency locked onto a molecular reference absorption line providing a very stable frequency behavior over the several year duration of the instrument life. The principle is well known for atomic clocks and has been adapted to the commercial availability of reliable telecommunication lasers. Semiconductor laser modules, optical fibers and fibered components are used to achieve a compact and reliable subsystem. The availability of such space compliant frequency stabilized laser sources opens new opportunities in the field of optical metrology such as interferometry and multi- aperture telescope co-phasing.
