摘要：

A strong axial tension increase induced by UV laser radiation is observed in the cores of single-mode optical fibers containing Bragg gratings, independently of the initial core stress. The induced index modulation of the gratings is linearly correlated to stress changes with a slope of(0.8 +/- 0.2) x 10(-4) mm(2)/kg. The phenomenon can be explained by a structural change of the glass in the fiber core into a more compact configuration.
