Abstract

The exposure of glass, embedded with copper nanoparticles, to a focused continuous wave laser results in controllable formation of microlenses on the surface of the glass. The dependence of the shape and the size of the microlenses on the exposure time and the laser power is discussed. The mechanism for heat and mass transfer under laser irradiation is proposed and is used to explain the relatively low powers required for the process, the shape of the microlenses, and the kinetics of the lens shape evolution during exposure. The fabrication of the microlenses of 2-50 μm in diameter is demonstrated
