Studies on an Improved Compact Physics Package for Rubidium Standards
Abstract
We present a compact laser-pumped rubidium frequency standard with a short-term frequency stability of 6 10-13 -1/2 and having a fundamental shot-noise limit below 8 10-14 -1/2. Our clock employs the physics package with a 25 mm diameter buffer-gas cell inside a compact microwave cavity, a newly developed laser head with integrated acousto-optical modulator to minimize the Light Shift effect, and a low-noise microwave synthesizer. This work paves the way for realization of clock stabilities y( ) < 1 10-13 -1/2 with a compact standard.
