Optical atomic clocks represent the state of the art in timekeeping, playing a key role in the scientific community and technological applications. Today, the most accurate optical clocks are based on ultracold atoms or ions, but their complexity and size limit their use outside of laboratory environments. In this context, the development of compact optical frequency standards based on warm atomic vapors has attracted increasing attention, with the potential to enable a wide range of applications in fundamental science, aerospace, and industry. This thesis, conducted in collaboration with the quantum sensing group at Leonardo Quantum Technologies Lab, presents the realization of an initial design of a warm-vapor rubidium atomic clock based on the two-photon transition driven at 778nm.
