Journal ArticleDOI
Progress toward the first observation of parity violation in chiral molecules by high-resolution laser spectroscopy.
Benoît Darquié,Clara Stoeffler,Alexander Shelkovnikov,Christophe Daussy,Anne Amy-Klein,Christian Chardonnet,Samia Zrig,Laure Guy,Jeanne Crassous,P. Soulard,Pierre Asselin,Thérèse R. Huet,Peter Schwerdtfeger,Radovan Bast,Trond Saue +14 more
TL;DR: The work of André Collet on bromochlorofluoromethane enantiomers, their synthesis, and their chiral recognition by cryptophanes made feasible the first generation of experiments presented in this article, and the common strategy to reach this goal is presented.
Journal ArticleDOI
Long-distance frequency dissemination with a resolution of 10(-17).
Christophe Daussy,Olivier Lopez,Anne Amy-Klein,Andrei Goncharov,M. Guinet,Christian Chardonnet,F. Narbonneau,Michel Lours,D. Chambon,Sébastien Bize,André Clairon,Georgio Santarelli,Michael E. Tobar,Andre N. Luiten +13 more
TL;DR: The link is used to compare the microwave reference and a CO2/OsO4 frequency standard that stabilizes a femtosecond laser frequency comb, demonstrating a resolution higher than the stability of the best microwave or optical clocks.
Journal ArticleDOI
Quantum cascade laser frequency stabilization at the sub-Hz level
B. Argence,Bruno Chanteau,Olivier Lopez,Daniele Nicolodi,Michel Abgrall,Christian Chardonnet,Christophe Daussy,Benoît Darquié,Yann Le Coq,Anne Amy-Klein +9 more
TL;DR: In this paper, the stability and frequency traceability of a quantum cascade laser on an optical frequency comb were demonstrated, with an accuracy of 2x10-15 and 10-14, respectively.
Journal ArticleDOI
86-km optical link with a resolution of 2 × 10-18 for RF frequency transfer
Olivier Lopez,Anne Amy-Klein,Christophe Daussy,Christian Chardonnet,F. Narbonneau,Michel Lours,Georgio Santarelli +6 more
TL;DR: In this paper, an urban 86 km fiber has been demonstrated with a resolution of 2×10-18 at one day measuring time using an optical compensator, with a reference carrier frequency of 1 GHz and a rapid scrambling of the polarisation state of the input light in order to reduce the sensitivity to polarisation mode dispersion in the fibre.
Journal ArticleDOI
Direct determination of the boltzmann constant by an optical method
Christophe Daussy,M. Guinet,Anne Amy-Klein,Khelifa Djerroud,Yves Hermier,S. Briaudeau,Christian J. Bordé,Christian Chardonnet +7 more
TL;DR: The Doppler width is deduced which gives a first measurement of the Boltzmann constant k(B) by laser spectroscopy, and should contribute to a new definition of the kelvin.
