Features of anisotropic discrete diffraction of the signal Gaussian beam in cascade-induced lattice created by two crossed pump waves in the quadratically nonlinear medium are investigated. The transitions from diffraction of a signal beam in free space to discrete diffraction and then to waveguiding in induced lattice are traced with increasing pump intensity. The diffractionless propagation of a tilted beam is obtained.
Keywords: photonics, cascade interaction, induced structures, optical arrays
