We　compare　Balmer-alpha　(H-alpha)　and　Balmer-beta　(H-beta)　emissions　from　high-power　(1.0-6.0　kW)　hydrogen　inductively　coupled　plasmas　(ICPs),　and　propose　region　I　(0.0-2.0　kW),　region　II　(2.0-5.0　kW),　and　region　III　(5.0-6.0　kW).　In　region　I,　both　H　a　emission　intensity　(I-alpha)　and　H-beta　emission　intensity　(I-beta)　increase　with　radio　frequency　(RF)　power,　which　is　explained　by　the　corona　model　and　Boltzmann＇s　law,　etc.　However,　in　region　II,　I-alpha　almost　remains　constant　while　I-beta　rapidly　achieves　its　maximum　value.　In　region　III,　I　a　slightly　increases　with　RF　power,　while　I-beta　decreases　with　RF　power,　which　deviates　significantly　from　the　theoretical　explanation　for　the　H-alpha　and　H-beta　emissions　in　region　I.　It　is　suggested　that　two　strong　electric　fields　are　generated　in　high-power　(2.0-6.0　kW)　hydrogen　ICPs:　one　is　due　to　the　external　electric　field　of　high-power　RF　discharge,　and　the　other　one　is　due　to　the　micro　electric　field　of　the　ions　and　electrons　around　the　exited　state　hydrogen　atoms　in　ICPs.　Therefore,　the　strong　Stark　effect　can　play　an　important　role　in　explaining　the　experimental　results.
