强泵浦二能级系统的荧光光谱的特征在于在各种系统中观察到的Mollow三重态，从原子到量子点和超导量子比特。我们从理论上研究了量子阱中强泵浦子带间跃迁的荧光。我们的研究结果表明，这样的系统的多电子性质导致通常的Mollow理论的修改。特别地，荧光光谱中的中心峰的强度成为电子相干性的函数，从而允许通过荧光强度测量获得二维电子气的相干时间。
The fluorescence spectrum of a strongly pumped two-level system is characterized by the Mollow triplet that has been observed in a variety of systems, ranging from atoms to quantum dots and superconducting qubits. We theoretically studied the fluorescence of a strongly pumped intersubband transition in a quantum well. Our results show that the many-electron nature of such a system leads to a modification of the usual Mollow theory. In particular, the intensity of the central peak in the fluorescence spectrum becomes a function of the electron coherence, allowing access to the coherence time of a two-dimensional electron gas through a fluorescence intensity measurement.
