We show how polarisation measurements on the output fields generated byparametric down conversion will reveal a violation of multi-particle Bellinequalities, in the regime of both low and high output intensity. In this caseeach spatially separated system, upon which a measurement is performed, iscomprised of more than one particle. In view of the formal analogy with spinsystems, the proposal provides an opportunity to test the predictions ofquantum mechanics for spatially separated higher spin states. Here the quantumbehaviour possible even where measurements are performed on systems of largequantum (particle) number may be demonstrated. Our proposal applies to bothvacuum-state signal and idler inputs, and also to the quantum-injectedparametric amplifier as studied by De Martini et al. The effect of detectorinefficiencies is included.Comment: 12 pages, 12 figure
