Abstract
A theoretical analysis of a traveling-wave difference-frequency-generation problem in three-dimensional space was performed. We found that, under a su itable hypothesis of low conversion efficiency in anisotropic nonlinear cry stals, the nonlinear interaction gives a diffraction-free propagation condi tion for particular J(0) Bessel beams and modulation instability phenomena for other J(0) Bessel beams.
