Electromagnetically induced transparency in cold rubidium atoms
We report experimental studies of electromagnetically induced transparency in {Lambda}-type and ladder-type atomic systems realized in {sup 87}Rb atoms cooled and confined in a magneto-optical trap. Complete transparency is observed in the {Lambda}-type system with a moderate coupling field. Comparison between the two systems reveals that at the line center of a weak probe transition, destructive interference occurs for the {Lambda}-type system, whereas constructive interference occurs for the ladder-type system. We discuss conditions of complete transparency in the {Lambda}-type system that contains hyperfine magnetic sublevels. Our experimental measurements for the two systems agree with theoretical calculations based on simple three-level {Lambda}-type and ladder-type models. {copyright} 2001 Optical Society of America
