摘要: Preliminary results from an experimental study of slow light in anti-relaxation-coated Rb vapour cells are presented, and the construction testing such described. The ground state decoherence rate allowed by coated cell walls leads to a dual-structured electromagnetically induced transparency (EIT) spectrum with very narrow (< 100 Hz) peak on top broad pedestal. Such EIT permits optical probe pulses propagate greatly reduced group velocity two time scales. Ongoing efforts optimize pulse delay systems discussed.
