Abstract
A new approach for producing long period fibre gratings by exposure of the optical fibre to high-intensity femtosecond pulses at λ = 264 nm is presented. Different types of fibres were investigated and it was found that strong attenuation peaks (16-28 dB) can be induced in H2-loaded fibres.
