Abstract

Starting from the equations describing electron moving, we obtained the analytical function of the electron moving in laser fields. Besides the first and the second harmonics, it includes the third and the fourth harmonics. It is shown that high-order harmonics can be excited in laser-plasma interactions. In general, the order of the harmonics is larger, its coefficient is smaller. In this paper, we compare the coefficient of the first and the second harmonics, its ratio is larger than 1.
