We theoretically and numerically investigate the spin fluctuations induced in a thermal atomic ensemble by an external fluctuating uniaxial magnetic field, in the context of a standard spin noise spectroscopy (SNS) experiment. We show that additional

We perform spin noise spectroscopy experiments in metastable helium atoms at room temperature, with a probe light whose frequency is blue detuned from the D _0 line. Both circular birefringence fluctuations (Faraday noise) and linear birefringence fl

Light induced non-equilibrium spin noise spectroscopy is theoretically and experimentally shown to be an efficient technique to reveal the structure and the coherent effects in the probed transition. Indeed, using metastable helium, the spin noise sp

We isolate a novel four-wave mixing process, enabled by coherent population trapping (CPT), leading to efficient phase sensitive amplification. This process is permitted by the exploitation of two transitions starting from the same twofold degenerate

Vertical External Cavity Surface Emitting Lasers (VECSELs) IX.
The generation of optically carried radio frequency (RF) is an important issue in the area of microwave photonics (MWP), which has gained tremendous developments and has a bright future [1]. Dual-frequency vertical-external-cavity surface-emitting la

International audience; We present a 10 GHz optoelectronic oscillator (OEO) based on optical amplification. The setup uses a 1-km of standard optical fiber at 1.5 μm and a semiconductor optical amplifier (SOA). The phase noise is -90 dBc/Hz at 100 H
