摘要

实验研究了具有连续弛豫的三能级超导系统中双色波的非弹性散射，该系统与波导作为开放空间强耦合。得到了散射电磁场的一阶时间分辨相关函数。结果表明，散射场是光相干的，非弹性散射光子的光谱功率密度分布与激发场的振幅有关，具有多重结构。用开放量子系统理论的标准方法成功地描述了所获得的依赖关系。

Resonance Fluorescence in a Three-Level Superconducting System with Resonant Bichromatic Pumping of Transitions

In this work, inelastic scattering of bichromatic waves on a three-level superconducting system with successive relaxation of levels, which is strongly coupled to a waveguide serving as an open space, is experimentally studied. The first-order time-resolved correlation functions of the scattered electromagnetic field are obtained. It is shown that the scattered field is optically coherent, and the distribution of the spectral power density of inelastically scattered photons has a multiplet structure with respect to the amplitude of the excitation field. The obtained dependences are successfully described by standard methods of the theory of open quantum systems.
