Multi-frequency telecom fibered laser system for potassium laser cooling
Charbel Cherfan, Maxime Denis, Denis Bacquet +7
We describe a compact and versatile multi-frequency laser system for laser-cooling potassium atoms, by frequency doubling a fiber-optic telecom beam ( or ~nm). L…
Acetylene-based frequency stabilization of a laser system for potassium laser cooling
Charbel Cherfan, Isam Manai, Samir Zemmouri +4
We demonstrate a laser frequency stabilization technique for laser cooling of Potassium atoms, based on saturated absorption spectroscopy in the C-Band optical telecommunication wi…
An Ultra-Stable Referenced Interrogation System in the Deep Ultraviolet for a Mercury Optical Lattice Clock
S. T. Dawkins, R. Chicireanu, M. Petersen +5
We have developed an ultra-stable source in the deep ultraviolet, suitable to fulfill the interrogation requirements of a future fully-operational lattice clock based on neutral me…
Doppler-free spectroscopy of the 1S0-3P0 optical clock transition in laser-cooled fermionic isotopes of neutral mercury
M. Petersen, R. Chicireanu, S. T. Dawkins +5
We have performed for the first time direct laser spectroscopy of the 1S0-3P0 optical clock transition at 265.6 nm in fermionic isotopes of neutral mercury laser-cooled in a magnet…
Accumulation of chromium metastable atoms into an Optical Trap
R. Chicireanu, Q. Beaufils, A. Pouderous +5
We report the fast accumulation of a large number of metastable 52Cr atoms in a mixed trap, formed by the superposition of a strongly confining optical trap and a quadrupolar magne…
Accumulation and thermalization of cold atoms in a finite-depth magnetic trap
R. Chicireanu, Q. Beaufils, A. Pouderous +6
We experimentally and theoretically study the continuous accumulation of cold atoms from a magneto-optical trap (MOT) into a finite depth trap, consisting in a magnetic quadrupole…
