Laser Cooling with Ultrafast Pulse Trains
Abstract
The goal of this contract was to investigate a novel laser-cooling technique that uses femtosecond lasers to extend the range of ultracold atomic species. During this grant work was performed to significantly advance construction of the apparatus for laser cooling of hydrogen and in characterization of the hydrogen beam. The following were achieved: 1) 3 kW laser intensity in a test resonator toward laser guiding of hydrogen, 2) generated multi-Watt ultrafast pulses at 1944 nm toward a cooling laser at 243 nm, 3) improved characterization of the hydrogen beam dissociation fraction. Additionally, steps toward proof-of-principle ion experiments with the novel laser cooling technique were made by improving the ion fluorescence signal by an order of magnitude and rebuilding the linear ion trap used for two-photon spectroscopy.
