Abstract
Laser-induced velocity-dependent light shifts have been used to compensate the Doppler broadening of an atomic transition. The unidirectional feature of this technique allowed us to observe a forward/backward asymmetry in the amplified spontaneous emission from an excited sodium vapor, switched on by a pulse of laser light.Keywords
