Self-steering partially coherent beams

WebIn this work, the self-focusing property of a partially coherent beam with a non-uniform correlation structure propagating in a non-linear medium is investigated. The analysis of the evolution of beam width reveals that the coherence structure plays a vital role in the self-focusing formation. http://top.electricalandcomputerengineering.dal.ca/PDFs/My%20Papers/OPEX2024.pdf#:~:text=In%20particular%2C%20self-steering%20partially%20coherent%20beams%20have%20been,their%20cross-spectral%20density%20shape%20on%20free%20space%20propagation.
