Electromagnetically-induced transparency in potassium microcell and its application

Abstract

The electromagnetically-induced transparency (EIT) resonance in a potassium microcell with a vapor column thickness of L = 30 μm on the D1 line of the 39K isotope was studied. The experimentally obtained width of EIT-resonance is 60 times narrower than the Doppler width of the potassium atom. In an external longitudinal magnetic field, the EIT-resonance splits into three spectrally narrow components. The theoretical curves calculated using the Rabi–Breit formula are in good agreement with the experimental results.
