Role of high nitrogen-vacancy concentration on the photoluminescence and Raman spectra of diamond
M. Jani, M. Mrózek, A. M. Nowakowska +3
We present a photoluminescence (PL) and Raman spectroscopy study of various diamond samples that have high concentrations of nitrogen-vacancy (NV) color centers up to multiple part…
Atomic-state diagnostics and optimization in cold-atom experiments
Krystian Sycz, Adam M. Wojciechowski, Wojciech Gawlik
We report on the creation, observation and optimization of superposition states of cold atoms. In our experiments, rubidium atoms are prepared in a magneto-optical trap and later,…
Coherent population oscillations with nitrogen-vacancy color centers in diamond
M. Mrozek, A. Wojciechowski, D. S. Rudnicki +4
We present results of our research on two-field (two-frequency) microwave spectroscopy in nitrogen-vacancy (NV-) color centers in a diamond. Both fields are tuned to transitions be…
Saturated-absorption spectroscopy revisited: atomic transitions in strong magnetic fields (20 mT) with a micrometer-thin cell
A. Sargsyan, A. Tonoyan, R. Mirzoyan +3
The existence of cross-over resonances makes saturated-absorption spectra very complicated when external magnetic field B is applied. It is demonstrated for the first time that the…
Nonlinear Faraday Rotation and Superposition-State Detection in Cold Atoms
Adam Wojciechowski, Eric Corsini, Jerzy Zachorowski +1
We report on the first observation of nonlinear Faraday rotation with cold atoms at a temperature of ~100 uK. The observed nonlinear rotation of the light polarization plane is up…
Optimal geometry for efficient loading of an optical dipole trap
Andrzej Szczepkowicz, Leszek Krzemien, Adam Wojciechowski +6
One important factor which determines efficiency of loading cold atoms into an optical dipole trap from a magneto-optical trap is the distance between the trap centers. By studying…
