Abstract
We report experimental studies of electromagnetically induced transparency in A-type and ladder-type atomic systems realized in Rb-87 atoms cooled and confined in a magneto-optical trap, Complete transparency is observed in t he A-type system with a moderate coupling field. Comparison between the two systems reveals that at the line center of a weak probe transition, destru ctive interference occurs for the A-type system, whereas constructive inter ference occurs for the ladder-type system. We discuss conditions of complet e transparency in the A-type system that contains hyperfine magnetic sublev els. Our experimental measurements for the two systems agree with theoretic al calculations based on simple three-level A-type and ladder-type models. (C) 2001 Optical Society of America.
