Based on our first principle simulation, (1) we have obtained the rescattering electron momentum distribution in the intense laser field, and illustrated the physical origination of the non-sequential double ionization of He using the obtained rescattering electron momentum ; (2) we have discovered the mechanism of the laser assisted photoionization of atoms and molecules, and proposed a way to control the transparent of materials by the intense laser in atto-second time domain and the proposal method has been used in experiments.
