Absorption line shape recovery beyond the detection bandwidth limit: application to the precision spectroscopic measurement of the Boltzmann constant
François Rohart, Sinda Mejri, Papa Lat Tabara Sow +8
A theoretical model of the influence of detection bandwidth properties on observed line shapes in laser absorption spectroscopy is described. The model predicts artificial frequenc…
A revised uncertainty budget for measuring the Boltzmann constant using the Doppler Broadening Technique on ammonia
Cyril Lemarchand, Sinda Mejri, Papa Lat Tabara Sow +6
We report on our on-going effort to measure the Boltzmann constant, kB, using the Doppler Broadening Technique. The main systematic effects affecting the measurement are discussed.…
Ultra-stable long distance optical frequency distribution using the Internet fiber network
Olivier Lopez, Adil Haboucha, Bruno Chanteau +3
We report an optical link of 540 km for ultrastable frequency distribution over the Internet fiber network. The stable frequency optical signal is processed enabling uninterrupted…
Cascaded multiplexed optical link on a telecommunication network for frequency dissemination
Olivier Lopez, Adil Haboucha, Fabien Kéfélian +6
We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Int…
High-resolution optical frequency dissemination on a telecommunication network with data traffic
Fabien Kéfélian, Olivier Lopez, Haifeng Jiang +3
We transferred the frequency of an ultra-stable laser over a 108 km urban fiber link comprising 22 km of optical communications network fiber simultaneously carrying Internet data…
86-km optical link with a resolution of 2.10-18 for RF frequency transfer
Olivier Lopez, Anne Amy-Klein, Christophe Daussy +4
RF frequency transfer over an urban 86 km fibre has been demonstrated with a resolution of 2.10-18 at one day measuring time using an optical compensator. This result is obtained w…
