Influence of the laser excitation linewidth on the parameters of EIA resonances in <sup>87</sup>Rb Open
The influence of the spectral linewidth of single-frequency lasers on the parameters of the electromagnetically induced absorption resonances in rubidium vapour is examined. We use two counter-propagating pump and probe beams to prepare hi…

Remote detection of the conductivity of current-carrying metallized traces Open
The weak magnetic fields generated by a current-carrying metallized traces are detected in view of their applications in bionic systems and neural-electrode interface technologies. The traces are formed by femtosecond laser processing of t…

Level-crossing resonances on open atomic transitions in a buffered Cs vapor cell: Linewidth narrowing, high contrast, and atomic magnetometry applications Open
The ground-state Hanle effect (GSHE) in alkali-metal atomic vapors using a\nsingle circularly polarized wave underlies one of the most robust and simplest\ntechniques in atomic magnetometry. This effect causes a narrow\n(subnatural-width) …

Coherent optical spectroscopy characterization of the magnetic properties of oriented Fe3O4 nanoparticles Open
Magnetite (Fe 3 O 4 ) nanoparticles are widely used in microwave components, such as microwave absorbers and anti-reflection coatings. Their magnetic properties are important for these applications. In this work, the weak magnetic field cr…

Dual-beam electromagnetically-induced absorption resonance in a <sup>87</sup>Rb cell with antirelaxation coating Open
Destruction of the laser-induced coherence in the ground state of alkali atoms manifests itself as an ultra-narrow resonance in the atomic spectrum. Depending on the geometry of irradiation and observation, the coherent spectroscopy studie…

Nonlinear enhanced-absorption resonances in compact alkali-vapor cells for applications in quantum metrology Open
We review three laser spectroscopy schemes developed recently for observation of high-contrast enhanced-absorption nonlinear resonances in small alkali-vapor cells. In our experiments, optical transitions within the cesium D1 line are invo…

Electromagnetically induced absorption resonances in Hanle-configuration prepared in a paraffin coated <sup>87</sup>Rb cell Open
We present an experimental investigation of electromagnetically-induced absorption (EIA) at the D 1 line of 87 Rb contained in an anti-relaxation coated vacuum optical cell. The configuration includes a pump and a probe beam propagating in…

Stray magnetic field influence on the CPT resonance in a coated Rb vacuum cell Open
Interaction of a resonant laser beam with an atomic absorption medium creates population redistribution and interference between atomic levels. This anisotropy of the medium is experimentally observed as coherent population trapping (CPT) …
