Fabrication of micrometer size laser-induced periodic surface structures (ripples)on single crystalline silicon by laser beam irradiation of wavelength (810 nm) in HFelectrolyte has been reported. Nonlinear changes of the refractive index are observeddue to the interaction of laser light with silicon nanoparticles. Spatial self-phasemodulated optical fringes were used to study the nonlinear optical response ofnanocrystalline silicon produced by laser-induced etching process.
