Abstract
Abstract: The electromagnetically induced transparency (EIT) phenomenon is studied using a nanometric thin (L = 795 nm) Rb vapour layer. EIT-type resonances that are formed in three different energy-level systems are reported. It is demonstrated that the EIT resonance which is formed in a Λ-system where the ground levels are separated by the hyperfine splitting (EITH-resonance) has the smallest linewidth (~10 MHz). The EIT resonance which is realized in a Λ-system formed by the Zeeman sublevels of the Fg = 2 → Fe = 1 transition (EITZ-resonance) has a larger linewidth (~14 MHz). The EITV-resonance which is formed in the V-system has the largest linewidth (~40 MHz). The uniqueness of the EIT phenomena reported here is that they can be formed in different types of Λ-systems even for L < 1 μm. The splitting of the EITZ-resonance into two components in a transverse magnetic field is reported. The theoretical model well describes the experiment.
