Abstract: Coherent, optically dressed media composed of two-level molecular systems without inversion symmetry are considered as all-optically tunable sources of coherent radiation in the microwave domain. A theoretical model and a numerical toolbox are developed to… read more here.

DOI: 10.1103/physreva.100.043822
Abstract: A theoretical model based on two-point scatterers is suggested to investigate scattering of partially coherent radiation by a non-Hermitian localized structure, invariant under the simultaneous symmetry operations of parity inversion and time reversal. Within the… read more here.

DOI: 10.1103/physrevapplied.9.024004
Abstract: Coherent radiation produced by relativistic charged bunches is nowadays of great interest for useroriented applications and high-resolution diagnostics. Here we present experimental results obtained by using a temporal monitor based on the electro-optical sampling that… read more here.

Abstract: In this work the coherence properties of the synchrotron radiation beam from an X-ray undulator in a fourth-generation storage ring are analyzed. A slightly focused X-ray beam is simulated using a wavefront propagation through a… read more here.

DOI: 10.1364/ol.44.004363
Abstract: The physical aspects of partially coherent radiation interacting with deterministic non-Hermitian periodic materials remain largely unexplored in the statistical optics literature. Here, we consider the scattering of partially coherent radiation by a deterministic periodic medium,… read more here.
