Tailoring on-axis spectral density with circularly coherent light beams Korotkova, O. de Sande, J. C. G. Santarsiero, Massimo Martínez Herrero, María Rosario Piquero Sanz, Gemma María Gori, Franco © 2022 Optica Publishing Group. Funding. Ministerio de Economía y Competitividad (PID2019-104268 GB-C21). The on-axis cross-spectral density (CSD) of a beam radiated by a stationary source with a circular coherence state and a Gaussian spectral density is obtained in the closed form. It is revealed that the on-axis CSD is expressed via the Laplace transform of the source's degree of coherence or the Hilbert transform of the corresponding pseudo-mode weighting function. Such relations enable efficient tailoring of the on-axis spectral density, as we show with a slew of numerical examples. 2023-06-22T10:45:06Z 2023-06-22T10:45:06Z 2022-05-15 journal article 0146-9592 10.1364/OL.458262 https://hdl.handle.net/20.500.14352/71586 http://dx.doi.org/10.1364/OL.458262 https://opg.optica.org eng PID2019-104268 GB-C21 open access Optica Publishing Group
