Formation of adatom density gratings on a substrate by channeling an atomic beam through a pulsed laser standing wave under a completely off-resonant condition

Summary form only given. We show that a microsecond laser standing wave with much higher electric fields has the same focusing power as a cw laser standing wave at near resonance condition. We further propose an experimentally practical setup that implements such a concept and show that even with a transversely uncooled atomic beam, we should be able to produce adatom density gratings on a substrate with good contrast ratios. We expect the findings to be applicable to all atoms and atomic clusters.
