Abstract

A detailed investigation has been carried out into the output characteristics of a fiber laser forming, as it does the basis of an optical sensor system, in terms of its wavelength, signal intensity and linewidth, and the output spectrum when each individual fiber Bragg grating, acting as the reflectors of the laser system, has been allowed to respond to temperature in a wavelength-matched normal Bragg grating-based laser configuration. An analytical model has been created reflecting the relationship between the grating bandwidth and the temperature under each operational condition and the results obtained have significant implication for the optimum design of this type of fiber laser-based sensors. Additionally, experiments were performed to investigate the output characteristics of a fiber laser-based sensor when used for temperature measurement.
