Fast all-optical nuclear spin echo technique based on EIT
Abstract: We demonstrate an all-optical Raman spin echo technique, using electromagneticallyinduced transparency (EIT) to create the pulses required for a spin echo sequence:initialization, pi-rotation, and readout. The first pulse of the sequence inducescoherence directly from a mixed state, and the technique is used to measure the nuclearspin coherence of an inhomogeneously broadened ensemble of
