Paper Abstract

New germanosilicate glasses with high photosensitivity were fabricated and studied. Addition of sodium produced an increase of 6-fold Ge ions and the appearance of a UV absorption band at 285 nm in the as cast glasses. Laser exposure produced bleaching of such band, when present. Further studies are needed to correlate the two phenomena and find out the best composition in terms of photosensitivity. A new tin sodium silicate glass was also fabricated: glass fibers were produced and high temperature stable gratings were obtained by irradiation with a UV laser.
