Description

In this study, we present a high-performance laser frequency stabilization method that utilizes modulation transfer spectroscopy (MTS) on the rubidium 87 D$_2$ transition line. The frequency instability is evaluated with beating signal of two frequency-locked external cavity diode lasers (ECDL), and reached a short-term stability of 4.5×10$^{−14}$/√τ and did not exceed 2×10$^{−12}$ until 10$^5$ s. To the best of our knowledge, this is the best performance reported with the rubidium 87 D$_2$ transition.
