Form birefringence originating from self-assembly of the bulk nanograting structures in silica glass with various anion dopants (OH, Cl and F) was induced by the femtosecond laser pulses. Despite of the almost similar nanostructure, the photoinduced birefringence can be changed by the anion dopants in glass. Larger birefringence can be induced in silica glass doped with higher Cl ion concentration. Even if F-doped silica glass indicates lower thermal stability, its lifetime could be evaluated to be at least several billion years. This article is protected by copyright. All rights reserved.
