Laser System for Developing a New Type of Atom Trap (DURIP)
Abstract
This grant is for instrumentation of a laser system for use in developing a new type of atomic trap, an atomic hydrogen trap that operates in the microkelvin regime. The laser system is designed to provide radiation at 243 nm in order to drive the 1S to 2S two-photon transition in atomic hydrogen. The system is based on a Coherent Model 699-21 Dye Laser, that is driven by a Model 200-K3 krypton ion laser. This generates 486 nm radiation which is frequency doubled in an external ring cavity. The system has been assembled and successfully operated. It delivers 5 mW of 243 nm radiation, which is, to our knowledge, a new record. The laser has been stabilized against cavity with a spectral noise of less than 2Hz. The laser system purchased under this grant is a vital component of our program to study hydrogen at ultra low temperatures, and also to carry forward laser spectroscopy to new regimes of precision.
