Abstract:

Research on this AASERT grant was focussed on the optical spectroscopy of trapped cold hydrogen for use as a spectroscopic tool and as a means of studying the gas. The grant supported research by two graduate students. During the grant an optical signal on the 1S - 2S transition in cold trapped hydrogen was observed, opening the way to a new form of ultra high resolution spectroscopy. The optical signal will also provide a valuable tool for manipulating a Bose condensate in hydrogen. The condensate can absorb two photons form a single running wave. The recoil is enough to sweep the atoms out of the trap, creating a new type of atom laser beam.
