摘要：
Based on the cesium 6S(1/2) -6P(3/2) -8S(1/2) ladder-type system, electromagnetically-induced transparency (Err) is further investigated in a room-temperature vapor cell. When the probe laser is locked to one of the hyperfine transitions between the ground state 6S(1/2) (F = 3) and the intermediate state 6P(3/2) while the coupling laser scans the transition between the intermediate state 6P(3/2) and the excited state 8S(1/2) the spectrum has a flat background improving the spectral resolution. The theoretically calculated EIT spectral profiles from a multi-level ladder-type model are consistent well with the obtained experimental phenomena.
