The permanent refractive index change induced by ultrashort laser pulses in zinc phosphate glasses has been investigated both at the surface and in bulk. At the sample surface, irradiations have been performed by using loosely focused single fs-laser

We report on the response of glass to focused femtosecond (fs) laser pulses during waveguide fabrication in a commercial sodium aluminum phosphate glass (Schott IOG-1). Single-pass longitudinal translation of IOG-1 glass with respect to the focused l

Waveguides were fabricated in fused silica using kHz and MHz repetition rate femtosecond lasers. Raman and fluorescence microscopy showed increases in 3-membered rings for both cases and fewer NBOHC-defects when writing with the MHz laser.

Summary form only given. We have written waveguides as long as 1 cm in silica glasses by tightly focusing femtosecond laser pulses from a regeneratively amplified Ti:sapphire laser (125 fs, 800 nm, 1 kHz) using a microscope objective and translating

Structural changes associated with femtosecond laser fabrication of waveguides and Bragg gratings in fused silica were analyzed using optical microscopy and laser spectroscopy. Using 800 nm femtosecond lasers with a kilohertz repetition rate and vari

Waveguides were written in fused silica using both a femtosecond fiber laser with a 1MHz pulse repetition rate and a femtosecond amplified Ti:sapphire laser with a 1kHz repetition rate. Confocal Raman and fluorescence microscopies were used to study
