Bruce Física, Astronomía y Matemáticas group velocity Ultrashort pulses temporal spreading group velocity dispersion The chromatic dispersion of optical materials causes an optical pulse to spread as it propagates through the material. The pulse spreadingis produced by the dependence of the group velocity on the frequency. In this paper we evaluate the temporal spreading of a pulse as itpropagates through optical glass. We evaluate the dependence of group velocity on frequency in terms of the dependence of the phaserefractive index of the glass on the wavelength of light. The dependence of the refractive index on the wavelength in glass is well knownthrough the Sellmeier formula. Results are presented for 50, 80 and 100 fs pulses propagating a distance L, in BK7, SF14 and Fused SilicaSchott optical glasses and verified by a model of the sum of Gaussian modulated frequencies 2008 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57054210 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
