Abstract

The process of electromagnetically induced transparency (EIT) was investigated using two different probe radiations in Cs atomic vapor: in the first case probe radiation– transmission through a nanocell (NC) with the formation of EITT; in the second–selective reflection (SR) of laser radiation from the boundary of the atom-dielectric vapor (dielectric is nanocell window) with the formation of EITSR. To form EIT resonances, we used two continuous narrow-band lasers with λ = 852 nm and a nanocell with an atomic vapor column thickness in the range of 150–1500 nm. A comparison of the formation of EIT resonance in the first and second cases was carried out. Probe radiation containing EITT and EITSR-resonances propagates in opposite directions. It is noted that in a few cases, the formation of EIT resonance is more effective using SR radiation. The splitting of the EITSR-resonance in the longitudinal magnetic field into seven equidistant components was recorded, which allows remote monitoring of the magnetic field.
