Nano-structural arrays were fabricated by channeling pulsed atomic beams through an intensity-modulated optical standing wave with a time-varying atom focal length. The fabrication was achieved by channeling a laser-ablation produced pulsed atomic beam through a synchronously modulated cw laser standing wave at off-resonance condition. The method proposed is independent of the spectral specifics of atoms and provides an effective cooling in the longitudinal direction.
