Absorption of Unshifted Scattered Light by a Molecular I2 Filter in Brillouin and Raman Scattering

Abstract
A simple molecular I2 vapor filter is described which can attenuate the unshifted scattered light in Brillouin and Raman scattering by greater than 108 with a background attenuation of less than 10, i.e., a discrimination ratio of > 107 : 1.
