Self-bending and filamentation effect due to optical nonlinearity properties is presented by 4-(4-pentenyloxy) benzonitrile. While we increased the power of cw argon laser multiline form 100 mW to 1W the central spot shows self-bending, and next the filamentation effect is present.
In this work we present the formation of dark photonic lattices in negative nonlinear medium. Bright periodic lattices are generated by interference technique and propagated through 1 cm of length of nonlinear medium (R6G with acetone). The dependence with the laser (Ar) power and the geometry selected are showed. Three very interesting cases were obtained: two dimensional dark photonic lattices (2D),...
Auto-diffraction and nonlinear properties of organic material is presented. Develop of rings by 4-(4-pentenyloxy)benzonitrile after being irradiated by a laser beam while the power is increased and nonlinear refraction index measured by Z-scan technique was investigated.
The problem of discrete light is very important from the physical point of view. Waveguides arrays, discrete solitons, optical switching are some applications of periodic structures. Experimental results obtained by periodic structures used in nonlinear liquids media are shown. In particular, we study self-focusing effect in CS2 with amplitude mask 2D with different arrays of circles periodically...
