Overtone Vibrations of OH Groups in Fused Silica Optical Fibers.
Abstract
The OH-stretching fundamental, and the first, second, and third OH overtone vibrations have been examined using pure and GeO2 - doped graded index, fused silica optical fibers having OH contents from less than 1ppm to greater than 1,000 ppm. The previously reported component substructure of the fundamental vibrations of fused silica. Several new vibrations were uncovered and assigned. Examinations of deuterated OH samples helped to verify the assignments. The spectral broadening produced by GeO2 was interpreted in terms of a wider range of environments seen by the OH oscillators, compared to pure fused silica. (Author)
