摘要

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