Opt. 33, 4508-4515 (1994). doi: 10.1364/AO.33.0045080003-6935http://hdl.handle.net/10919/46908We study how Gaussian laser-beam profiles can be modified into a desired form using acousto-optic Bragg diffraction. By exploiting the angular dependence of Bragg diffraction of plane waves by acoustic gratings, we demonstrate that the conversion from a Gaussian-profile beam into either a near-field or a far-field flattop profile is possible.application/pdfenIn CopyrightPeriodically modulated mediaLaser-beamsArticle - Refereedhttp://www.opticsinfobase.org/ao/abstract.cfm?URI=ao-33-20-4508https://doi.org/10.1364/AO.33.004508
