如果假设两个或多个经典阻尼振子独立发射，则它们的相干发射显然违反了能量守恒定律。为了解决这个明显的悖论，有必要包括与合作衰减相关的效应，其中每个振子修改其他振子的阻尼率。我们将展示如何将这些影响包括在两个辐射振荡器和一行N个振荡器。讨论了合作衰减、光相干瞬态和超辐射之间的关系。
Coherent emission from two or more classical damped oscillators leads to an apparent violation of conservation of energy if the oscillators are assumed to emit independently. To resolve this apparent paradox, it is necessary to include effects related to cooperative decay, wherein each oscillator modifies the damping rate of the other oscillators. We show how these effects are included for two radiating oscillators and for a line of N oscillators. The relation between cooperative decay, optical coherent transients, and superradiance is discussed.
