(A) Shape factor for different wavelengths for a scattering angle of 90° versus filament length as predicted by Rayleigh-Gans theory (Eqs (2), (3), (4)). The shape factor determines the normalized scattered light intensities for different filament lengths. (B) The ratio of the scattered light intensities (594/405 nm) increases monotonically during filament elongation up to a filament length of 7 ULFs. To see this figure in color, go online.
