High efficiency holmium-doped triple-clad fiber laser at 2120 nm
Bastien Beaumont, Pierre Bourdon, Alexandre Barnini +3
We developed a new holmium-doped triple-clad fiber (Ho-3CF), reducing the clad diameter to improve the overlap between pump and doped-core, and the holmium concentration to reduce…
A compact differential gravimeter at the quantum projection noise limit
Camille Janvier, Vincent Ménoret, Sébastien Merlet +3
Atom interferometry offers new perspectives for geophysics and inertial sensing. We present the industrial prototype of a new type of quantum-based instrument: a compact, transport…
Multi-Dimensional Atom Optics and Interferometry
Brynle Barrett, Pierrick Cheiney, Baptiste Battelier +2
We propose new multi-dimensional atom optics that can create coherent superpositions of atomic wavepackets along three spatial directions. These tools can be used to generate light…
Generation of high-purity, low-temperature samples of K for applications in metrology
L. Antoni-Micollier, B. Barrett, L. Chichet +4
We present an all optical technique to prepare a sample of K in a magnetically-insensitive state with 95\% purity while maintaining a temperature of 6 K. This versatile p…
