A modified Faraday rotation method is developed using a nanocell filled with cesium vapor. Formed atomic lines have a spectral width 1.5–2 times narrower than those obtained by the Faraday rotation method. In magnetic fields of B = 5000–7000 G, a

In this communication, we present experimental results on the preparation of magneto-optical resonances in potassium. The magneto-optical resonances are registered in Hanle configuration, i.e. monitoring the atomic fluorescence vs the applied magneti

In this paper we discuss a novel use of a Cs-filled optical cell with micrometric thickness. The cell intrinsically contains an extremely small number of Rb atoms. When heated up to temperatures around 350 $$^\circ $$C, the vapor in the cell consists

Distortion of the spectrum of the D1-line of 85Rb in optical cells with an antirelaxation coating on the inner walls of the cell is studied. The spectrum shape is found to be significantly dependent on the velocity and direction of changes in the las

A new device is designed: it consists of a nanocell (NC) filled with Rb atom vapors and placed in a vacuum chamber. When the pressure in the chamber changes in the range 0–1 atm, the NC thickness is smoothly varied in the range L = 140–1700 nm, w

Significant modification of the spectrum of the D1 line of 85Rb in optical cells with high quality antirelaxation coating on the walls is studied experimentally and theoretically analyzed. The spectral profiles of hyperfine transitions are found to b

We report on the investigation of narrow sub-Doppler-width resonances observed at the D2 line of Cs atoms (Fg = 4 → Fe = 3, 4, 5 hyperfine transitions), confined in thin optical cells. These cells have a thickness of L = 6λ (λ = 852 nm) and L = 7
