英文摘要	We calculate the lifetime of both the o-Ps and the p-Ps positronium annihilation decay Ps -> gamma gamma in the strong circular polarized laser field. We take a strategy of the factorization to separate the effects caused by the Coulomb interaction and the strong laser field interaction. It is factorized in the time direction but not in the space direction. Our results show that in the laser with long wavelength and high intensity, the lifetimes of those Ps states are dramatically increased. For CO2 laser with 10 mu m wavelength and 10(13) W/cm(2) intensity, lifetime of the spin-single positronium is increased by 10(8) times. Our result is consistent with those obtained by solving the Schodinger equation. This effect may be useful for the high harmonic generation (HHG) effects provided with the Ps [Phys. Rev. Lett. 70 (1993) 774; Phys. Rev. Lett. 93 (2004) 013601].
