The effect of losses on the visibility of mesoscopic entanglement states is analyzed on the basis of a recently proposed generation scheme which amplifies a quantum seed through stimulated down-conversion. The visibility of the entanglement is shown with the amplifier working above threshold, for short interaction times.
