Non-symmetrical vortex beam shaping in VECSEL laser arrays

We propose and numerically test, to our knowledge, a novel concept for asymmetric vortex beam generation in a degenerate vertical external cavity surface emitting laser (DVECSEL). The method is based on a phase-locking ring array of lasers created…

Controlled HPHT annealing of SiV-doped nanodiamonds at SOLEIL synchrotron: structural and optical investigations

Diamonds and nanodiamonds (NDs) containing quantum color centers, such as nitrogen-vacancy (NV) centers, have been widely studied in recent years for their promising applications across various fields, including cryptography and telecommunications,…

Probing interactions by spin noise spectroscopy

Dans les systèmes magnétiques, la spectroscopie du bruit fondamental dû aux fluctuations aléatoires du spin, appelée spectroscopie du bruit de spin (SNS), est réalisée optiquement en mesurant les fluctuations de la rotation de Faraday subie par un…

Wavefront shaping enhanced nano-optomechanics down to the quantum precision limit

We introduce wavefront shaping as a tool for optimizing the sensitivity in nano-optomechanical measurement schemes. We perform multimode output analysis of an optomechanical system consisting of a focused laser beam coupled to the transverse motion…

Single Graphene Quantum Dots in a molecular crystal

Les boîtes quantiques de graphène (abrégé GQD en anglais) sont des objets nanométriques composés de centaines d'atomes de carbone. Ces nouveaux émetteurs quantiques fonctionnent dans le visible et sont très prometteurs pour des applications en…

Optimal Control of Levitated Nanoparticles through Finite-Stiffness Confinement

Optimal control of levitated nanoparticles subjected to thermal fluctuations is a challenging problem, both theoretically and experimentally. In this Letter, we compute the time-dependent harmonic confining potential that steers, in a prescribed…
