Airy beams generated by the four-wave mixing (FWM) process in a homogeneous atomic medium is investigated.It is shown that Airy beams generated by both pure- FWM (PFWM) and dressed- FWM (DFWM)processes exhibit accelerating dynamics with a parabolic trajectory.The acceleration rate of these Airy beams can be dramatically modified by changing the detuning and strength of the external fields applied to the system.Due to nonlinear change of atomic coherence and the refractive index of resonant atoms induced by the dressing field,the amplitude suppression (enhancement) and the deflection position variation of DFWM signals can be achieved simply by changing the detuning of the dressing field.Airy beams generated via the FWM process can possibly be a powerful tool for delivering optical power,resonant particle manipulation and optical information processing.
