Atomic dipole trap formed by a Gaussian standing wave

We suggest an atomic dipole trap which is produced by two counter-propagating Gaussian beams with different waists. This set-up creates an intensity dip in axial and radial directions near the node of the standing wave and can be used as an atom trap for blue detuning of the light. We simulated the behaviour of two level atoms in this trap using the dressed state Monte-Carlo method and we show that it gives a goad trapping when the residual intensity at the bottom of traps is small.
