Archivio Istituzionale della RicercaWe propose a signal-theory approach to estimate the contribution from laser intensity noise to the short-term stability of compact atomic clocks based on optical detection.

This is of fundamental importance, since laser intensity noise is currently one of the main limiting factors of vapor-cell clocks.

Abstract
We propose a signal-theory approach to estimate the contribution from laser intensity noise to the short-term stability of compact atomic clocks based on optical detection. We remove the approximation of white intensity noise, which is usually found in literature, and propose a method for a more faithful estimate, given an arbitrary noise spectrum at the input. This is of fundamental importance, since laser intensity noise is currently one of the main limiting factors of vapor-cell clocks.
