We discuss the phenomenon of coherence-driven gain: the effect that oscillating atomic dipoles can amplify or attenuate a light field depending on the phase difference between dipoles and field. No inversion of atomic population is required to increase the field. This is in contrast to population-dr
The pump pulse induces nonstationarity and coherence in the medium. It is shown that there are mechanisms of absorption (emission) which depend on the phase difference between the field and the matter oscillator. They are principally different from conventional absorption and stimulated emission. Th
