POAM in starlight: Analysis of Seven Years of SAM measurements

摘要

At the Starfire Optical Range in 2011, the first measurements of photonic orbital angular momentum in starlight were made. Although that survey conclusively demonstrated that POAM exists in starlight, the survey was limited. We have subsequently obtained access to the SAM data archive with its seven years of data. Here the SAM data is analyzed to include the two metrics, branch point density, ρ, and the conversion efficiency 77, that were used in the analysis of the 2011 observations.
