    "abstract": "We calculate the relative amplitude of orbital angular momentum (OAM)\nentangled photon pairs from the spontaneous parametric down conversion. The\nresults show that the amplitude depends on both the two Laguerre indices l, p.\nWe also discuss the influences of the mostly used holograms and mono-mode\nfibers for mode analyzation. We conclude that only a few dimensions can be\nexplored from the infinite OAM modes of the down-converted photon pairs.",
