摘要

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.
