Long-period fiber grating fabrication by high-intensity femtosecond pulses at 211 nm

Using high-intensity (110-200 GW/cm/sup 2/) 250-fs 211-nm laser pulses and a point-by-point technique, the efficiency of long-period grating inscription in H/sub 2/-loaded standard telecom Corning SMF-28 and H/sub 2/-free photosensitive B-codoped Fibercore fibers was studied and compared with those...
