Year: 2024
Type: article
Abstract: We present absolute frequency measurements of a laser stabilized using an offset sideband locking technique on the P(49)24-1 rovibrational transition of 127 I 2 near 556 nm. The P(49)24-1 transition is offset by 4.8 GHz from the intercombination transition of 171 Yb. A dual-tone electro-optical modulator is employed to bridge this frequency gap, enabling frequency stabilization of the 556 nm laser near the Yb transition, achieving a fractional frequency stability of 1.2 × 10 −11 at one second. We thoroughly characterize the frequency shifts associated with this locking scheme, with typical systematic effects fractional uncertainties of 9 × 10 −12 .
