Improvements to A Transportable Atomic Fountain Laser system
Paul D. Kunz, Vladislav Gerginov, Thomas P. Heavner, Steven R. Jefferts
We are developing a transportable rubidium (Rb) atomic fountain frequency standard which uses independently phase-locked diode lasers for laser-cooling. At this point in time, we have not demonstrated sub-Doppler (υKelvin) atom temperatures using out phased-locked laser scheme. However, we present measurements indicating the problem is due to insufficient phase-coherence between the cooling lasers. We are presently building a new generation of laser locking electronics which we believe will allow for sub-Doppler laser cooling of the Rb atoms. Additionally, we discuss a number of improvements we have made to the system since our last publication.
