J. Maufoy et al., EXPERIMENTAL-STUDY OF THE SELF-FOCUSING PROCESS CONVERGING TOWARDS SPATIAL SOLITONS IN PHOTOREFRACTIVE MEDIA, Journal of the Korean Physical Society, 32, 1998, pp. 453-455
The paper describes an experimental apparatus and experimental results
which allows to measure a spatial self-focusing of a laser beam throu
gh a Bi12TiO20 (BTO) photorefractive crystal. The comparison with a (1
+1) theoretical model confirms the occurrence of the transient and ste
ady state solitons.
