A Simplified Laser and Optics System for Laser-Cooled Rb Fountain-Frequency-Standards
Paul D. Kunz, Thomas P. Heavner, Steven R. Jefferts
We are developing a simple and robust laser and optics system suitable for a transportable laser-cooled Rubidium (Rb) atomic fountain frequency standard. This system uses DFB (Distributed Feedback) diode lasers and a frequency offset locking scheme to generate the optical frequencies need for laser-cooling, launching, post-cooling, and detection of Rb atoms. Here we describe the early results from this project and anticipated performance of a compact, transportable Rb fountain frequency standard using this laser system. Additionally, this system will be useful for non-transportable laser-cooled atomic-frequency-standards.
