The stimulated emission in the quasi-periodic photonic crystals is investigated in this paper. It was found that there are some interesting phenomenons in that structure. The lasing is more abundant and stronger compared with that in periodic crystals. More stimulated emission peaks appear when the size and the gain increase, and some lasing peaks are independent on incident direction, isotropic. These lasing peaks maybe come from the localization of the disorder in the quasi-periodic photonic crystals.
