  The Raman scattering spectra from magnetic excitations in an
antiferromagnetic spin-1/2 two leg ladder is investigated for weak and strong
interladder coupling. In the first case, a cusp in the Raman intensityis
obtained at a frequency twice the gap. In the second case, a peak at twice the
gap replaces the cusp. We discuss the relevance of our calculation to recent
experiments on CaV2O5 and Sr14Cu24O41.
