Abstract

Photovoltaic laser beam degradation in lithium niobate (LiNbO3) has been investigated through a finite-differences beam propagation method for nonlinear media. The simulations use a two-center model (Fe2+ <-> Fe3+ , Nb-Li(4+) <-> Nb-Li(5+)) that has been recently proved to be necessary to successfully describe the photorefractive effect in nominally pure LiNbO3. Refractive index profiles and intensity and phase beam profiles have been calculated for a wide intensity range and several material distances. A good agreement is obtained on comparing simulations and experimental data. This includes self-defocusing for moderate intensities and the complex beam profile structures appearing for high intensities, providing a complete description of this nonlinear optical phenomenon.

In the year of publication of the work, 2014, it was in position , thus managing to position itself as a Q1 (Primer Cuartil), in the category Atomic and Molecular Physics, and Optics.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-06:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 4.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 4 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).
