Abstract

We have investigated the lin||lin CPT signal in the ⁸⁷Rb D1 manifold when the atoms are contained in low pressure buffer gas cells. We predict the achievable clock frequency stability, basing our considerations on the signal-to-noise measurements. We show that a short-term stability of about 2·10^-11 τ^1/2 may be reached in a compact system using a modulated VCSEL, this value is mainly limited by the detection noise level and can be improved up to a factor 4 by using high frequency phase sensitive detection. Under the same experimental condition a challenging short-term stability of 1-3·10^-13 τ^1/2 can be achieved by using the PL ECDLs.
