摘要

We demonstrated the enhanced second harmonic generation (SHG) fromasingle sodium niobate (NaNbO₃) nanocrystal by approaching a metal tip on top of it. By scanning a laser-focused NaNbO₃ nanocrystal with a gold-coated tip, the mapping of the enhanced SHG from the nanocrystal was obtained. We observed that the SHG of the single NaNbO₃ nanocrystal was strongly enhanced with the gold-coated tip on the top of it. And the enhancement factor showed strong dependence on the excitation polarization and the excitation power. An over 12-fold tip enhancement was observed when the excitation power was 12 mW.
