Gaussian　beam　in　the　vertical　cavity　surface　emitting　laser　(VCSEL)　has　important　application　in　3D　sensing　and　optical　communications,　due　to　its　concentrate　energy　at　center　and　long　propagation　distance.　However,　its　beam　quality　under　high　power　tends　to　be　serious　degradation　and　become　annular　hollow　distribution,　severely　limiting　the　use　of　VCSEL.　Here,　the　anisotropic　elliptical　oxide　aperture　VCSEL　(AEOA-VCSEL)　was　designed　to　achieve　high-power　Gaussian　beam　with　high-quality　via　anisotropic　modes　control.　The　saturation　output　power　reached　up　to　8.2　mW　under　low　injection　current,　to　our　best　knowledge,　which　was　the　highest　power　generated　in　single　VCSEL　device.　Moreover,　the　AEOA-VCSEL　can　control　the　output　beam　profile　only　by　adjusting　injection　current,　and　could　also　homogenize　the　mode　spacing　among　adjacent　high-order　modes.　The　facile　preparation　process　and　low　cost　makes　the　device　present　great　potential　in　augmented　and　virtual　reality　(AR/VR),　3D　sensing　and　optical　communications.　©　2023　Elsevier　Ltd
