Two-dimensional　in-phase　coherently　coupled　vertical　cavity　surface　emitting　laser　(VCSEL)　array　with　high　beam　quality　was　fabricated　by　proton　implantation.　Indium-tin-oxide　(ITO)　current　spreading　layer　was　employed　to　improve　the　uniformity　of　the　injection　current.　This　makes　a　coherent　array　to　operate　in　in-phase　mode　even　in　a　relatively　larger　scale.　The　appropriate　thickness　of　ITO　current　spreading　layer　was　obtained　by　experiment　(80　nm).　The　procedure　of　proton　implantation　defined　array　is　considerably　simple　and　low　cost.　A　3　x　3　in-phase　coherently　coupled　array　with　2.4　degrees　(1.28　x　D.L.)　of　lobe　beamwidth　was　achieved.　It　sufficiently　demonstrates　the　advantages　of　the　high　beam　quality　of　the　in-phase　coherently　coupled　arrays.　The　output　power　of　the　array　was　up　to　4.5　mw　under　pulse-wave　condition.
