Abstract :
This work is devoted to studying the possibilities of using a femtosecond laser facility and a scanning atomic-force microscope (AFM) for nonlinear optical diagnostics. The developed technique ensures an optical resolution of 30 nm for gold nanoparticles. It is shown that the presence of the AFM tip significantly affects the nonlinear optical response of separate gold nanoparticles.
