Spatial and temporal solitons are at the core of many physical, geological, biological, transmission and information processing and other problems. However, in most cases we have focused on their steady behavior, and therefore on homogeneous media and their single soliton eigenvalues spectrum. This has been done even in the case of an all optical simultaneous loss and amplification, where we have assumed stability of those eigenvalues. However, the transient behavior has received little attention, often disregarded under a generic pulse reshaping or experimentally diafragmed as often occurs in large amplifiers. But such transient behavior can be frozen in a periodic nonhomogenous media, tandems, where such behavior corresponds to the soliton convergence in each tandem media, producing a regular but not steady behavior. We discuss the resonant pulse propagation in a two level atom media tandem, described by a real convergence and a Kerr intensity dependent nonlinearity, described by a complex convergence.
