Abstract

Interest in magnetically induced (MI) transitions of alkali metal atoms is caused by the fact that their intensities can exceed the intensities of regular atomic transitions in a wide range of magnetic field (200 - 4000 G). The goal of this work was to form and study, for the first time, an electromagnetically induced transparency (EIT) resonance in a strong magnetic field using a probe radiation tuned to |Fg = F; mF = 0-> Fe = F; mF = 0> MI transition, which is forbidden in zero magnetic field. Two narrow-band linearly-polarized cw diode lasers were used to form a EIT resonance on a lambda-type system of Cs atomic D2 line in a strong transverse magnetic field (up to 1000 G). The resonance was formed in Cs atomic vapor nanocell with the atomic vapor column thickness of 850 nm.
