Query: High efficiency preparation of single trapped atoms using blue detuned
  light assisted collisions   We report on a procedure by which we obtain a 91% loading efficiency of
single 85Rb atoms in an optical microtrap. This can be achieved within a total
preparation time of 542 ms. We employ blue detuned light assisted collisions to
realize a process in which only one of the collision partners is lost. We
explain the mechanism for efficiently loading a single atom and discuss the
factors that limit the final efficiency.
