Multi-Gaussian Schell-model source with a complex coherence state

Abstract: The effects of non-trivial phase of the source degree of coherence on the far-field spectral density for the class of one-dimensional, multi-Gaussian Schell-model beams are explored. While in the absence of the phase, the flat-top spectral density profile with a Gaussian edge drop is symmetrically formed in the far field about the optical axis, various phase functions introduce asymmetric modifications to such distribution. Since the phase of the source degree of coherence must be an odd function, three such e… Show more

“…The first row of Figure 4 shows the case where δ α and δ β have the same value for all items and the values of L is small. The CDC resembles a multi-Gaussian Schell-model case [18], the coherence curve presents a spirallike cochleoid profile, and the far-field spectral density becomes a laterally shifted flat-top profile. As can be seen from the second row of Figure 4 for large values of L, the CDC oscillates more, the spiral coherence curve is more complex, and p(v) presents a comb profile on one side of the optical axis.…”

“…The aim of this paper is to develop a theoretical framework for analytical modeling of such pulses. Our approach is based on the temporal analog of a sliding function method recently introduced for the spatial counterpart of a coherence state [32][33][34][35]. We also suggest a detailed experimental procedure for realization of these new non-stationary pulses and verify its validity with the help of a computer simulation.…”

“…Very recently, a general method for structuring the CDC with non-trivial phase distribution via sliding function has been developed [14]. Then, several phase functions have been introduced to the source coherence states, which leads to special effects for the intensity distribution in the far field [15][16][17][18][19][20].…”
