On z-coherence in self-focusing Gori, F. Martínez Herrero, María Rosario Piquero Sanz, Gemma María Sande, J. C. G. de Korotkova, O. Santarsiero, M. ©2022 Optica Publishing Group Both the intensity distribution and the degree of coherence between pairs of points along the propagation axis (z-coherence) are derived in closed form for a phenomenon of self-focusing produced by circularly coherent light. The first confirms results previously obtained numerically, while the second exhibits new complex features. The physical interpretation is obtained by a suitable pseudo-modal expansion that suggests an analogy with a simple two-mode structure. 2025-12-11T19:20:59Z 2025-12-11T19:20:59Z 2022-03-24 journal article F.
