Stability limitations from optical detection in Ramsey-type vapour-cell atomic clocks
Résumé |
In today's state of the art compact vapour-cell atomic clocks
relying on the pulsed Ramsey-type interrogation, optical detection
noise is a major limitation to the achievable short-term stability.
In this communication, the influence of the optical detection time
on the clock's short-term stability is investigated and a new
analytical expression is developed to precisely predict the
stability performance, taking into account the details of the
optical detection phase of a Ramsey-type atomic clock. The theory
is in good agreement with the experimental results. It is applied
for evaluating the clock's shot-noise limit. |
