This is an ABSTRACT ONLY. The definitive version is published in the Journal of Optics Express, vol.20(21), pp 23589-23597Orbital angular momentum (OAM) entanglement is investigated in the Bessel-Gaussian (BG) basis. Having a readily adjustable radial scale, BG modes provide an alternative basis for OAM entanglement over Laguerre-Gaussian modes. We show that the OAM bandwidth in terms of BG modes can be increased by selection of particular radial wavevectors and leads to a flattening of the spectrum, which allows for higher dimensionality in the entangled state. We demonstrate entanglement in terms of BG modes by performing a Bell-type experiment and showing a violation of the Clauser-Horne-Shimony-Holt inequality. In addition, we use quantum state tomography to indicate higher-dimensional entanglement in terms of BG modes.enOrbital angular momentumOAMBessel-Gaussian beamsEntangled Bessel-Gaussian beamsArticleMcLaren, M., Agnew, M., Leach, J., Roux, F., Padgett, M., Boyd, R., & Forbes, A.
