    "abstract": "We report an experimental investigation of electromagnetically induced\ntransparency in a multi-level cascade system of cold atoms. The absorption\nspectral profiles of the probe light in the multi-level cascade system were\nobserved in cold Rb-85 atoms confined in a magneto-optical trap, and the\ndependence of the spectral profile on the intensity of the coupling laser was\ninvestigated. The experimental measurements agree with the theoretical\ncalculations based on the density matrix equations of the rubidium cascade\nsystem.",
