In Amsterdam We have recently produced the first two-dimensional lattice of magnetic microtraps for ultracold atoms based on patterned magnetic films [1]. Ultracold rubidium atoms are transferred to hundreds of individual microtraps, each cloud hovering 10 micrometers above the chip surface and separated by ~20 micrometers. We are currently investigating highly excited Rydberg states of the atoms, used to mediate long-range interactions between neighbouring microtraps. This could allow entanglement of mesoscopic ensembles of atoms and paves the road toward quantum information processing with neutral atoms. We have built a dedicated laser system using 780 nm and 480 nm narrow-band diode lasers stabilised to a two-photon electromagnetically induced transparency resonance in a Rubidium vapour cell. We can excite Rydberg states from n=19 up to n~100. We have used this system to excite and image Rydberg atoms in ultracold rubidium gas confined in a surface magneto-optical trap. We are now studying the influence of the nearby (magnetic and conducting) chip surface on the Rydberg excited atoms. . LIGHT AMPLIFICATION by STIMULATED ELECTRON RADIATION. Question:. In movies, laser beams are always shown as bright pencils of light streaking through the air or space. If you were to look from the side at a beam from a powerful laser, would you be able to see that laser beam as it travels past you?. Technical Advances Towards Terabit Networking. Geoff Bennett.
