Selected Studies on High Performance Laser-Pumped Rubidium Atomic Clocks

In this communication, we report on our recent investigations related to the development of a compact high performance laser-pumped vapor cell Rubidium atomic clock. These studies include the evaluation of alternative technologies for key components of the clock such as the laser source and the microwave cavity. We also present new spectroscopic and metrological investigations aiming to improve the medium and long-term frequency stability (microwave power shift, light shift and environmental effects).
