Imaging the collective excitations of an ultracold gas using statistical correlations
Romain Dubessy, Camilla De Rossi, Thomas Badr +2
Advanced data analysis techniques have proved to be crucial for extracting information from noisy images. Here we show that principal component analysis can be successfully applied…
A detector for continuous measurement of ultra-cold atoms in real time
C. Figl, L. Longchambon, M. Jeppesen +4
We present the first detector capable of recording high-bandwidth real time atom number density measurements of a Bose Einstein condensate. Based on a two-color Mach-Zehnder interf…
Experimental investigation of amplitude and phase quantum correlations in a type II OPO above threshold: from the non-degenerate to the degenerate operation
Julien Laurat, Thomas Coudreau, Laurent Longchambon +1
We describe a very stable type II optical parametric oscillator operated above threshold which provides 9.7 0.5 dB (89%) of quantum noise reduction on the intensity differenc…
Non-linear and quantum optics of a type II OPO containing a birefringent element Part 2 : bright entangled beams generation
Laurent Longchambon, Julien Laurat, Thomas Coudreau +1
We describe theoretically the quantum properties of atype-II Optical Parametric Oscillator containing a birefringent plate which induces a linear coupling between the orthogonally…
Non-linear and quantum optics of a type II OPO containing a birefringent element Part 1: Classical operation
Laurent Longchambon, Julien Laurat, Thomas Coudreau +1
We describe theoretically the main characteristics of the steady state regime of a type II Optical Parametric Oscillator (OPO) containing a birefringent plate. In such a device the…
