Optimization of the diffraction efficiency in photorefractive crystals

The aim of this work is to study and to optimize the diffraction efficiency in sillenite BTO crystals. A theoretical analysis, where the effects of coupling beams are significant, is carried on. In addition, non-mobile transmission gratings are considered. The diffraction efficiency is obtained by u...

Se presenta un análisis teórico en donde los efectos de acoplamiento son tenidos en cuenta. Además, se consideran redes nomoviles de transmisión. La eficiencia de difracción es obtenida a través de la solución de las ecuaciones acopladas en el regimen on-Bragg usando el método de Runge-Kutta de orden 4 implementado en Matlab. La no uniformidad de las redes dentro del cristal, la actividad óptica del material y la polarización de los haces son tenidos en cuenta.Unidad de Investigación y Desarrollo OptimoCentro de Investigaciones Ópticas2017info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf181-186http://sedici.unlp.edu.ar/handle/10915/87624enginfo:eu-repo/semantics/altIdentifier/issn/0030-3917info:eu-repo/semantics/altIdentifier/doi/10.7149/OPA.50.2.49044info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:55:16Zoai:sedici.unlp.edu.ar:10915/87624Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:55:16.897SEDICI (UNLP) - Universidad Nacional de La Platafalse
