In this work we present a scheme to control the optical dipole trap potentialin an N-type four-level atomic system by using chirped femtosecond Gaussianpulses. The spatial size of the trap can be well controlled by tuning the beamwaist of the Gaussian pulse and the detuning frequency. The trapping potentialsplits with increasing Rabi frequency about the center of the trap, a behavioranalogous to the one observed experimentally in the context of trapping ofnanoparticles with femtosecond pulses. An attempt is made to explain thephysics behind this phenomenon by studying the spatial probability distributionof the atomic populations.
