Abstract

Motivated by the potential use of electromagnetically induced transparency (EIT) to measure atomic parity nonconservation (PNC), we have studied EIT and associated optical rotation for a three-level system in thallium vapor. EIT allows sub-Doppler resolution of the 6P1/2→6P3/2 mixed magnetic dipole, electric quadrupole transition at 1.28µm when 0.535−µm radiation acts on the 6P3/2→7S1/2 transition. Our measurements include rotation due to electromagnetically induced birefringence and Faraday rotation perturbed by EIT. We also identify a new method for determining the amplitude ratio E2/M1 for the 1.28−µm transition. The possible advantages of an EIT technique for measuring atomic PNC are discussed in the context of our results.
