Observation of Unidirectional Amplified Spontaneous Emission Induced by Velocity-Dependent Light Shifts

Observation of Unidirectional Amplified Spontaneous Emission Induced by Velocity-Dependent Light Shifts

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 observations of a forward/backward asymmetry in the amplified spontaneous emission from an excited sodium vapor, switched on...

Zusammenfassung: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 observations of a forward/backward asymmetry in the amplified spontaneous emission from an excited sodium vapor, switched on by a pulse of laser light.
