In this work experimental measurements showing formation of dark periodic lattices in negative nonlinear liquid medium are reported. These lattices were formed by the propagation of periodic patterns through a nonlinear liquid media. These periodic patterns were induced by interference of three plane waves. Here three interesting cases showing the evolution of bright into dark periodic lattices are reported. In the first case periodic lattices formed by dark spots were observed. In the second case a periodic lattice formed by a set of stripes was observed. Finally in the third case a periodic lattice showing a combination of stripes and dark spots is reported.
