Abstract
Lasers are used for the first time to control the production of antihydrogen (). Sequential, resonant charge exchange collisions are involved in a method that is very different than the only other method used so far—producing slow during positron cooling of antiprotons in a nested Penning trap. Two attractive features are that the laser frequencies determine the binding energy, and that the production of extremely cold should be possible in principle—likely close to what is needed for confinement in a trap, as needed for precise laser spectroscopy.
