Vortex beams carry orbital angular momentum (OAM) and this intrinsic property makes them prevalent in transferring this OAM to matter and to be used in quantum information processing. The authors explore an extra-cavity and intra-cavity approach in LG0l mode generation respectively. The outputs of a Porro-prism resonator are represented by “petals” and they show that through a full modal decomposition, the “petal” fields are a superposition of two LG0l modes.enVortex beamsPetalsLaguerre-Gaussian beamsPorro-prism resonatorSLMPhotonicsOpticsBeamsConference PresentationNaidoo, D., Aït-Ameur, K., & Forbes, A.
