Abstract :
We isolate nonlinear KTiOPO4 (KTP) nanocrystals and study them by second-harmonic generation (SHG) microscopy and atomic force microscopy (AFM). With both polarization analysis and defocused imaging of the emitted second harmonic field, we extract the Euler angles of the crystalline axes of a single nanocrystal. The nonlinear features and photostability of a single KTP nanocrystal make it a good candidate for a vectorial probe of electromagnetic near-fields and coherent imaging.
