Remote detection of HF molecules in open atmosphere with the use of tunable diode lasers

This paper sets out to present the results of a study of the feasibility of building a prototype device for prompt (on-line mode) remote measurements of HF trace quantities in atmosphere (with the optical length of up to 100 m, and a cat’s eye as a reflector) making use of near-infrared range diode...

Zusammenfassung:This paper sets out to present the results of a study of the feasibility of building a prototype device for prompt (on-line mode) remote measurements of HF trace quantities in atmosphere (with the optical length of up to 100 m, and a cat’s eye as a reflector) making use of near-infrared range diode lasers (DLs). The gas analyzer consisted of DLs operating at λ =1.28 μ, a telescopic system and a retro-reflector. The remotely measured HF sensitivity in atmosphere was better than 10 ppb.
