Raman scattering in optical fibers

In this paper we review the light scattering spectra of optical fibers and present new data on Raman spectra of optical fibers. The results include Raman spectra of fused silica fibers and effects of dopants and irradiation‐Large scattering volumes available in optical fibers afford one to detect low dopant concentrations and relatively weak second order spectra. Low frequency Raman spectra of optical fibers shows the expected non‐Debye type anomaly.
