a Scheme of the experimental set-up. b Expected and experimental pattern obtained for two circular spots of 200 µm diameter. Red circles represent the position of the spots of laser. c, d Optical micrographs of patterns of deviated cracks. e SEM micrograph of the pattern and the polystyrene nanoparticles in the inset. f Optical micrographs of a gold lines pattern, with g the corresponding SEM image. h Optical micrograph of a porous TiO2:SiO2 curved pattern with i the corresponding SEM image. The inset shows the porous structure.
