✦ Synopsis

We report the first demonstration of a technique by which an optically thick medium may be rendered transparent.

The transparency results from a destructive interference of two dressed states which are created by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent. The transmittance of an autoionizing (ultravio- let) transition in Sr is changed from exp( -20) without a coupling laser present to exp( -I ) in the pres- ence of a coupling laser.
