Watt-level single-frequency tunable Neodymium MOPA fiber laser operating at 915-937 nm
Sergio Rota-Rodrigo, Benoit Gouhier, Mathieu Laroche +8
We have developed a Watt-level single-frequency tunable fiber laser in the 915-937 nm spectral window. The laser is based on a neodymium-doped fiber master oscillator power amplifi…
Small Gold Nanorods with Tunable Absorption for Photothermal Microscopy in Cells
Edakkattuparambil Sidharth Shibu, Nadezda Varkentina, Laurent Cognet +1
Over the last decade, single-molecule optical microscopy has become the gold-standard approach to decipher complex molecular processes in cellular environments. [1-3] Single-molecu…
Accelerating GMM-based patch priors for image restoration: Three ingredients for a 100 speed-up
Shibin Parameswaran, Charles-Alban Deledalle, Loïc Denis +1
Image restoration methods aim to recover the underlying clean image from corrupted observations. The Expected Patch Log-likelihood (EPLL) algorithm is a powerful image restoration…
Spontaneous avalanche dephasing in large Rydberg ensembles
T. Boulier, E. Magnan, C. Bracamontes +6
Strong dipole-exchange interactions due to spontaneously produced contaminant states can trigger rapid dephasing in many-body Rydberg ensembles [E. Goldschmidt et al., PRL 116, 113…
A two-particle, four-mode interferometer for atoms
Pierre Dussarrat, Maxime Perrier, Almazbek Imanaliev +5
We present a free-space interferometer to observe two-particle interference of a pair of atoms with entangled momenta. The source of atom pairs is a Bose--Einstein condensate subje…
Quantum depletion of a homogeneous Bose-Einstein condensate
Raphael Lopes, Christoph Eigen, Nir Navon +3
We have measured the quantum depletion of an interacting homogeneous Bose-Einstein condensate, and confirmed the 70-year old theory of N.N. Bogoliubov. The observed condensate depl…
