摘要

Transmission phase gratings have been designed and fabricated in glass samples via implantation of helium and nitrogen ions of energies in the 500 keV -1.6 MeV range, through photoresist masks. Both mono- and multienergy implantations have been applied. Diffraction efficiencies of the gratings as function of the energy and dose of the ion implantation were measured.The phase profiles of the lines of the gratings have also been measured directly via interference and phase contrast-microscopy and scanning electron microscopy. Diffraction efficiencies up to 20% have been obtained.
