VILLAMIZAR AMADO, Astrid Lorena; ARIAS HERNANDEZ, Néstor Alonso; MOLINA PRADO, Martha Lucía  e  TEBALDI, Myrian. Analysis of the diffraction efficiency in transverse configuration in sillenite crystals Bi₁₂TiO ₂₀. Ciencia en Desarrollo [online]. 2018, vol.9, n.1, pp.113-117. ISSN 0121-7488.

A theoretical study on sillenite crystal where it obtained an analytics expression for diffraction efficiency in the on-Bragg regime in transverse configuration (K < 001 >) is realized. It is considered non-mobile transmission gratings. An analysis of diffraction efficiency considering the non-uniformity of gratings, material properties, external parameters the applied field or the intensity of beam input or polarization or the optical activity of the crystal beetwen others is realized.

Palavras-chave : Photorefractive crystals; diffraction efficiency.
