Determination of the Boltzmann constant by laser spectroscopy as a basis for future measurements of the thermodynamic temperature
Cyril Lemarchand, Khelifa Djerroud, Benoît Darquié +6
In this paper, we present the latest results on the measurement of the Boltzmann constant kB, by laser spectroscopy of ammonia at 10 ?m. The Doppler absorption profile of a ro-vibr…
A coherent optical link through the turbulent atmosphere
Khelifa Djerroud, Ouali Acef, Andre Clairon +4
We describe the realization of a 5 km free space coherent optical link through the turbulent atmosphere between a telescope and a ground target. We present the phase noise of the l…
First direct determination of the Boltzmann constant by an optical method
Christophe Daussy, Mickael Guinet, Anne Amy-Klein +5
We have recorded the Doppler profile of a well-isolated rovibrational line in the \nu2 band of 14NH3. Ammonia gas was placed in an absorption cell thermalized by a water-ice bath.…
