We report on the experimental generation of an entangled state with a spectrally pure heralded single-photon state and a weak coherent state. Our source, which was as efficient as that reported in our previous report, was much brighter than those reported in earlier experiments using similar configurations. This entanglement system is useful for quantum information protocols that require indistinguishable photons from independent sources.
