Single KTiOPO 4 nanocrystals , isolated from a flux‐grown powder, efficiently generate a perfectly stable and blinking‐free second‐harmonic field under non‐resonant femtosecond optical excitation (see image). For each individual nanocrystal, size and three‐dimensional orientation are determined using combined atomic force microscopy and optical techniques.
