Abstract
A modelocked erbium-doped fibre laser (EDFL) exhibited a 9.7% decrease in its pump laser output power and pulsewidth broadening from 9.2 to 300 ps following a 10.14 kGy(Si) gamma-ray irradiation. A decrease in the EDFL intra-cavity power from the combined effects of the pump laser degradation, and colour centre induced absorption in the fibre segments and other EDFL components was responsible for the broadening and long recovery times required for restoration of modelocking
