    "abstract": "We report on an experiment demonstrating the conservation of orbital angular\nmomentum in stimulated down-conversion. The orbital angular momentum is not\ntransferred to the individual beams of the spontaneous down-conversion, but it\nis conserved when twin photons are taken individually. We observe the\nconservation law for an individual beam of the down-conversion through\ncavity-free stimulated emission.",
