摘要：
In a Doppler-broadened ladder-type cesium atomic system (6S 1/2 -6P 3/2 -8S 1/2 ),this paper characterizes electro-magnetically induced transparency (EIT) in two different experimental arrangements,and investigates the influence of the double-resonance optical-pumping (DROP) effect on EIT in both arrangements. When the probe laser is weak,DROP is explicitly suppressed. When the probe laser is moderate,population of the intermediate level (6P 3/2 F’= 5) is remarkable,therefore DROP is mixed with EIT. An interesting bimodal spectrum with the broad component due to DROP and the narrow part due to EIT has been clearly observed in cesium 6S 1/2 F = 4-6P 3/2 F’= 5-8S 1/2 F’’= 4 transitions.
