Abstract

The tensile strength of fiber Bragg gratings is dependent on the type of UV laser exposure. The basic conclusion for the traditional method of producing gratings (exposure in the near-field region of a phase mask) is that the pulsed KrF excimer laser (248 nm) damages the fiber and the continuous wave frequency-doubled argon ion laser (244 nm) does not, provided that the fibers are handled carefully. Using the excimer laser at a low fluence (~5 mJ/cm2 pulse) and hydrogen loaded fiber, we demonstrate that Bragg gratings with an index change of 1.25x10-4 can be written. Although this index change is not enough to write a highly reflecting WDM grating, it is enough to write a weakly reflecting pump stabilization grating. The tensile strength of these fibers follow a Weibull distribution similar to pristine fiber with a median tensile strength of ~4.4 GPa (640 kpsi). A small percentage of the fibers are minimally damaged. As the fluence is increased, the median tensile strength decreases and the variability increases. The probability of damage from the laser as a function of the laser intensity suggests a damage mechanism related to laser-induced dielectric breakdown.
