Abstract
We extend the basic idea of inversionless amplification to a picosecond test pulse in the absence of initial optical coherences. The crucial role of population trapping by lower level Zeeman coherence in atomc samarium vapor (J=1⇆J’=0) is demonstrated experimentally and theoretically in a time separated preparation-test setup.Keywords
