An　accurate　far-field　intensity　distribution　model　of　coherent　VCSEL　array　is　established　based　on　Fraunhofer　diffraction　theory,　of　which　the　calculated　far-field　pattern　can　be　configured　by　tuning　the　phase　distribution　of　the　array.　In　experiment,　configurable　beam　emissions　are　achieved　in　two-dimensional　coherent　square　2　x　2　VCSEL　arrays　and　triangular　3-element　VCSEL　arrays　by　engineering　the　phase　distribution　of　the　array　through　simply　constructing　the　array　structure.　Single-lobe　beam,　double-lobe　beam,　and　four-lobe　beam　are　obtained　in　these　arrays.　Besides,　beam　shape　manipulation　is　also　realized　by　adjusting　the　ratio　of　horizontal　dimension　to　vertical　dimension　of　the　array.　The　experimental　results　are　in　good　agreement　with　the　calculated　results　from　the　established　theoretical　model.
