Abstract：

The　propagation　characteristics　of　elliptical　Airy　vortex　beams　(EAVB)　with　different　elliptical　parameter　and　topological　charges　are　demonstrated　experimentally　and　numerically.　Besides,　the　relationship　between　elliptical　parameter　and　detection　probability　of　the　orbital　angular　momentum(OAM)　is　analyzed　numerically.　The　results　show　that　elliptical　parameter　has　a　significant　impact　on　the　OAM　spectral　distribution　and　the　propagation　characteristics　of　the　EAVB.　The　EAVB　possess　an　elliptical　shaped　transverse　pattern　in　the　main　lobe　surrounded　by　a　series　of　rings　and　has　the　line　of　intensity　nulls　in　the　focal　plane.　It　also　has　two　focal　planes　during　the　propagation,　and　the　distance　between　the　two　focal　plane　becomes　shorter　with　the　increase　of　elliptical　parameter.　The　long　axis　of　the　intensity　ellipse　of　the　EVAB　rotates　90°between　the　second　focal　plane　and　the　first　focal　plane.　There　is　a　linear　relationship　between　OAM　detection　probability　and　the　elliptical　parameter.　The　experimental　results　are　in　good　agreement　with　theory,　which　will　be　helpful　for　the　application　of　EAVB　in　optical　trapping　and　optical　communication.　©　2022　Elsevier　B.V.
