Abstract

Silica glasses are important materials for laser application because of high thermal resistance and relatively lower non-linear refraction index than in silicated glasses. A new preparative technique for obtaining silica gel-glasses is presented. This technique permits us to prepare the silica glasses at low temperature. The preparation of silica gel-glasses with a small contamination of OH and CH maoities is possible by baking the samples in F₂ or Cl₂ atmosphere. The obtained glass rods were then drawn into fibers. The fiber attenuation was measured on 200 micrometer core diameter fibers using the cut-back technique and in agreement with the IEC 875-1 norm. It was found that the new glass has much lower attenuation characteristics at 1.55 micrometer. We believe that optimization of sol-gel processing will completely eliminate water impurity absorption.
