| Abstract: | The density of states for an ideal Bose gas in a γ-dimensional potential is obtained. Morever, the spatial distribution of particle numerical density is derived in the Thomas-Fermi semiclassical approximation. On this basis, the valid gain range of space for atom laser (that is the valid trapped range of ideal Bose gas in γ-dimensional potential) is given, and the influence of some important factors is also discussed. |

| Keywords: | γ-dimensional space Bose-Einstein condensation atom laser valid gain range of space |
