    "abstract": "We investigate the second-order non-linear interaction as a means to generate\nentanglement between fields of differing wavelengths. And show that perfect\nentanglement can, in principle, be produced between the fundamental and second\nharmonic fields in these processes. Neither pure second harmonic generation,\nnor parametric oscillation optimally produce entanglement, such optimal\nentanglement is rather produced by an intermediate process. An experimental\ndemonstration of these predictions should be imminently feasible.",
