Paper Abstract

In this paper we demonstrate high strength (Κ< 4 cm-1) grating imprinting using excimer KrF UV laser for underwater DFB fiber laser sensing applications. The FPGA-controlled stepping recording system allows for the recording of long (up to 52mm) gratings with error compensation, chirping and apodisation for side-lobe suppression and at arbitrarily high exposures. Batch recording of fibre gratings (4 fibres/mm) was also proposed and demonstrated.
