Keywords:

optical vortex,high-speed AFM

We developed high-speed atomic force microscopy (HS-AFM) combined with optical vortex setup so that we can capture movies of sample motions under optical vortex at the nanoscale. We observed surface relief formation in azo-polymer thin films under optical vortex irradiation using HS-AFM.
