After pre-irradiation in 10 À5 Torr vacuum, the 355 nm laser-induced damage threshold of fused silica decreased, while in air the damage resistance performance increased. The structure and defects of fused silica has been studied by means of Fourier transform infrared, Raman and Photoluminescence sp

## Abstract The numerical solution of a wave equation describing the propagation of the laser pulse of a few optical cycles in fused silica is obtained. Our numerical simulations closely follow the published experimental data. A shifting of the spectrum peak of the broadened pulse, depending on the
1-to-8 and 1-to-4 optical waveguide power splitters were fabricated using the focused 800 nm-amplified femtosecond laser to directly write a series of 1-to-2 Y-junction splitters in a fused silica glass sample. A shifted multi-scan technique was developed to substantially reduce the excessive insert
