Abstract This paper investigates the enhancement of Langmuir and ion-acoustic wave and the acceleration of the electron in collisionless plasma, in the presence of an external transverse field. Based on hydrodynamic equations, an equation formulizing the parametric instability was derived. Furthermore, the formula for ponderomotive force and the expression that describes the electron acceleration were obtained. The results show that Langmuir and ion-acoustic wave are enhanced and the charged particles can be accelerated by the coupling of wave-wave. In addition, it can be concluded that ponderomotive force, due to the coupling of the external field (pump) to the Langmuir wave (ion-acoustic wave), is the driving force to excite the parametric instability and comprises the high- and low-frequency components.
