Abstract
A novel and rapid laser ablation method for the fabrication of phase diffractive gratings in low-cost glass substrates is presented. The structures are characterized in terms of their shape and physical parameters by confocal microscopy and SEM microscopy. The first-order diffraction efficiency at normal incidence under 632.8 nm wavelength is shown. The influence of the overlap factor on the period grating is studied.
