碩士 === 國立成功大學 === 物理學系 === 102 === We report experimental observation of electromagnetically induced transparency (EIT) that both probe and coupling fields are π-polarized. The probe field will be absorbed strongly based on the Λ-EIT scheme of cold atomic ensemble of 87Rb due to the absence of the coupling field at one of Zeeman state. We use a pumping light to avoid this problem and restore the high transmission property of EIT. In order to observe the relation with the Doppler effect and transmission, we set the angle of the probe and coupling beams for 90 degrees, and infer the temperature of cold atomic ensemble is approximately 260 μK.
