    "abstract": "Stimulated emission of two photons is observed experimentally in the\nparametric amplification process and is compared to a three-photon interference\nscheme. We find that the underlying physics of stimulated emission is simply\nthe constructive interference due to photon indistinguishability. So the\nobserved signal enhancement upon the input of photons is a result of\nmulti-photon interference of the input photons and the otherwise spontaneously\nemitted photon from the amplifier.",
