    "abstract": "We consider the creation of polarization entangled light from parametric\ndown- conversion driven by an intense pulsed pump inside a cavity. The\nmulti-photon states produced are close approximations to singlet states of two\nvery large spins. A criterion is derived to quantify the entanglement of such\nstates. We study the dynamics of the system in the presence of losses and other\nimperfections, concluding that the creation of strongly entangled states with\nphoton numbers up to a million seems achievable.",
