“…The POP approach, instead, joints similar stabilities performances with a much simpler implementation, only one laser is used to alternatively pump and detect the atoms. The effectiveness of the POP technique is also demonstrated by the interest of several other laboratories that, following the seminal works done at INRIM, have undertaken the realization of a POP clock (Baryshev et al 2017;Dong et al 2017;Monahan et al 2019), obtaining in some cases outstanding results not far from those achieved by INRIM (Almat et al 2020;Shen et al 2020).…”

We present the results of 10 years of research related to the development of a Rubidium vapor cell clock based on the principle of pulsed optical pumping (POP). Since in the pulsed approach, the clock operation phases take place at different times, this technique demonstrated to be very effective in curing several issues affecting traditional Rb clocks working in a continuous regime, like light shift, with a consequent improvement of the frequency stability performances. We describe two laboratory prototypes of POP clock, both developed at INRIM. The first one achieved the best results in terms of frequency stability: an Allan deviation of σy(τ) = 1.7 × 10−13 τ−1/2, being τ the averaging time, has been measured. In the prospect of a space application, we show preliminary results obtained with a second more recent prototype based on a loaded cavity-cell arrangement. This clock has a reduced size and exhibited an Allan deviation of σy(τ) = 6 × 10−13 τ−1/2, still a remarkable result for a vapor cell device. In parallel, an ongoing activity performed in collaboration with Leonardo S.p.A. and aimed at developing an engineered space prototype of the POP clock is finally mentioned. Possible issues related to space implementation are also briefly discussed. On the basis of the achieved results, the POP clock represents a promising technology for future GNSSs.

The article presents the methods for calculating the stability of the rubidium frequency standards. To implement these methods, new software has been developed. Experimental measurements of telemetric parameters of the quantum frequency standard are processed using the developed software. The stability of the prototype of the rubidium standard has been determined using the proposed new algorithms.
