Abstract
We propose a double linewidth pseudo-Voigt profile to handle the spectral shape variances caused by short pulse interactions during the Brillouin scattering process in optical fibers. When short pulses are used, their broad frequency spectra contribute to the overall Brillouin spectrum. Hence, the convoluted spectrum consists of CW light scattering plus the broad frequency spectrum from the short pulse.
