Abstract :
Most near-field optical experiments are performed with fiber tips coated with an opaque metal layer. The resolution of such experiments is determined by the aperture size and is typically equal to 50 nm. Here we report the first experiment to implement near-field scanning optical microscopy (NSOM) with an uncoated fiber tip to map local SHG intensity from a KDP crystal surface.
