  • Abstract
    We present a compact physics package based on coherent population trapping (CPT) in rubidium 85. The architecture of the package is described along with results obtained using optical- and microwave spectroscopy. We also report the stability of the CPT resonance to variations in operating parameters such as microwave modulation power and vapour cell temperature. With this package we obtain a short term frequency stability σy(τ) = 7·10-11·τ-1/2 (τ <; 100 sec) and σy(τ) ~ 1·10-11 ( 100 sec <; τ <; 104 sec).
