A spectrometer using a monomode tunable diode laser as a source is described. The phase of the emission is controlled by the interference pattern given by a Michelson interferometer. The phase noise is thus drastically reduced and the wavenumber measurement precision is better than 10 8 . Also,...

4 The First Planetary TLS Instruments A tunable diode laser spectrometer was first considered for a planetary mission as part of the Cassini Huygens probe (Webster et al. 1990) during the European Space Agency (ESA) Phase A study. It was an open-path multi-channel instrument to measure ...
In general, a TDL laser spectrometer system is designed to detect a single gas using a single, specially fabricated, dedicated, laser diode. Occasionally, absorption transitions from different gases of interest may occur within the useful tuning range of a single laser, but such occurrences are ...
