Abstract

Collection-mode near-field scanning optical microscopy (NSOM) is used to map nanoscopic second-harmonic generation (SHG) in $N$-(4-nitrophenyl)-$\left(L\right)$-prolinol crystals. A spatial resolution of 98 nm is achieved. Near-field polarization-dependent SHG measurement is performed, and a local effective SHG susceptibility of $224\pm 18 \mathrm{pm}/\mathrm{V}$ is obtained.
