A　scheme　is　presented　for　generating　a　four-photon　coherent　state　via　the　degenerate　Raman　interaction.　The　scheme　does　not　need　classical　fields　to　manipulate　the　atoms.　Its　another　advantage　is　that　the　atomic　spontaneous　emission　can　be　neglected.　Therefore,　the　coherence　of　the　system　may　be　better　maintained.　The　scheme　can　be　generalized　to　generate　superposition　of　2　n　coherent　states　and　superposition　of　2n　two-mode　coherent　states.　The　coherent　states　in　each　mode　are　on　a　circle　symmetrically.　©　International　Academic　Publishers.
