Abstract

We describe a simple and cost-effective holographic method for the fabrication of surface-relief zone plates. The zone plate is inscribed by interference between the first- and second-order diffracted waves from an ion-etched Fresnel zone plate. The inscribed surface-relief zone plates are observed by atomic force microscope (AFM). The formation process of the surface grating and the mass diffusion in azo polymer are analyzed.
