Abstract

It has been shown¹ that when a spectral line whose profile is Gaussian is incident on a time-independent medium whose refractive index varies randomly with position in a prescribed manner, the spectrum of the scattered field is also Gaussian but is shifted in frequency and narrowed. It has also been shown that relative to the case when the scattering medium is completely spatially uncorrelated, the shift is always toward lower frequencies.
