  We present the results for a model calculation of resonant two-magnon Raman
scattering in a spin density wave (SDW) antiferromagnet. The resonant
enhancement of the two-magnon intensity is obtained from a microscopic analysis
of the photon-magnon coupling vertex. By combining magnon-magnon interactions
with `triple resonance` phenomena in the vertex function the resulting
intensity line shape is found to closely resemble the measured two-magnon Raman
signal in antiferromagnetic cuprates. Both, resonant and non-resonant Raman
scattering are discussed for the SDW antiferromagnet and a comparison is made
to the conventional Loudon-Fleury theory of two-magnon light scattering.
