Evanescent　coupled　fiber　laser　array　was　described　and　studied.　Array　modes　were　derived　by　applying　the　static　eigenmode/supermode　theory.　The　stability　of　output　power,　the　array　scalability　and　the　array　mode　were　analyzed　by　numerically　studying　the　dynamical　characteristics　of　the　laser　array　system.　The　array　modes　based　on　the　above　two　methods　were　compared　and　analyzed.　The　results　show　that　the　output　power　level　and　the　power　stability　are　directly　affected　by　the　phase　locking　property　and　the　relative　phase　errors　respectively.　With　the　increase　of　laser　elements,　the　total　output　power　of　the　array　increases　nonlinearly.　By　tracking　the　phases　of　array　elements　and　examining　the　laser　array　property　in　both　near　and　far　fields,　the　evidence　that　at　least　37　fibers　can　be　coherently　combined,　is　given.　With　the　increase　of　fiber　elements,　the　power　differences　between　central　element　and　its　neighbors　become　smaller　gradually.
