Abstract
An ability to predict absolute Raman intensities of the major spectral features in glasses in general is becoming increasingly important in association with the search for new optic fiber materials since the phenomenon of stimulated Raman scattering is an important mechanism in assessing the capabilities and limitations of such fibers in many applications. In this paper we recognize three rather general types of lattice vibrational mode which are potentially able to produce major Raman features in glasses and calculate their contributions to absolute integrated Raman scattering loss (in dB/km). A comparison with experiment is given for vitreous SiO2, GeO2, B2O3, BeF2 and P2O5. The extension to multicomponent glasses and full predictive capabilities of the derived formulae in a general context are discussed in the accompanying paper (part II).
