The excitation of plasma wake wave and acceleration of electrons after interaction between a high intensity ultrashort laser and underdense plasma using a particle in cell simulation is numerically studied. The results show that wake waves can be excited after the interaction between the single frequency or beat wave laser and underdense plasma, but the wake wave has larger strength and longer wavelength, then it can more efficiently accelerate electrons.
