摘要：

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 6P(1/2) --> 6P(3/2) mixed magnetic dipole, electric quadrupole transition at 1.28 mu m when 0.535-mu m radiation acts on the 6P(3/2) --> 7S(1/2) 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-mu m transition. The possible advantages of an EIT technique for measuring atomic PNC are discussed in the context of our results.
