Exploration of a vapor cell optical frequency standard scheme implemented using Doppler-free spectroscopy
We implement a compact optical frequency standard scheme with laser frequency locked to the 5S<sub>1/2</sub> (F = 2) - 6P<sub>3/2</sub> (F<sup>'</sup> = 3) transition of the second excited state of <sup>87</sup>Rb atoms in a 3 mm cubic glass cell, using a Doppler-free saturated absorption spectroscopy. The experimental results show the frequency stability at the level of 2.2 × 10<sup>-12</sup> at 1 s. Furthermore, we conduct an experimental study on the effect of a repump laser on the frequency performance of the saturated absorption spectroscopy optical frequency standard, providing valuable experimental results with reference values for implementing this type of optical atomic clock.
