Abstract :
Bragg grating inscription dynamics in large-index-difference N-doped silica fibres with and without fluorine in the cladding and isochronal annealing of such gratings are studied with regard to the UV-radiation energy density per pulse. Ultra-thermo-resistant gratings have been written at a high energy density per pulse
