  We consider Raman scattering of coupled two leg spin ladders in the
Fleury-Loudon regime. We derive the dependence of the intensity with
polarization of the incoming light and temperature and discuss the effect of
interaction of the elementary excitations on the shape of the spectrum. We show
that Raman scattering spectrum is sensitive to the effective dimensionality of
the coupled ladder system, making Raman scattering useful to discriminate true
ladder systems from quasi two dimensional spin gap systems.
