    "abstract": "Two different experimental techniques for preparation and analyzing\nsuperpositions of the Gaussian and Laguerre-Gassian modes are presented. This\nis done exploiting an interferometric method on the one hand and using computer\ngenerated holograms on the other hand. It is shown that by shifting the\nhologram with respect to an incoming Gaussian beam different superpositions of\nthe Gaussian and the Laguerre-Gaussian beam can be produced. An analytical\nexpression between the relative phase and the amplitudes of the modes and the\ndisplacement of the hologram is given. The application of such orbital angular\nmomenta superpositions in quantum experiments such as quantum cryptography is\ndiscussed.",
