Extended Data Fig. 1: Lattice and clock path.
From: Differential clock comparisons with a multiplexed optical lattice clock
Schematic diagram showing the lattice and clock beam paths for the interrogation the \(|{}^{1}{S}_{0},{m}_{F}=\pm 5/2\rangle \leftrightarrow |{}^{3}{P}_{0},{m}_{F}=\pm 3/2\rangle \sigma \)-transition. To interrogate the \(|{}^{1}{S}_{0},{m}_{F}=\pm 9/2\rangle \leftrightarrow |{}^{3}{P}_{0},{m}_{F}=\pm 9/2\rangle \)-transition, the first order diffraction clock beam is overlapped with the lattice by first using a long-pass dichroic beam splitter and subsequently transmitting through the polarized beam splitter, shown in the dashed blue box. The inset shows the corresponding orientations of the bias magnetic field (B) and the lattice and clock polarizations (ε). Abbreviations: PBS, polarized beam-splitter; DBS, dichroic beam-splitter; AOM, acousto-optic-modulator; PD, photo-diode; HWP, half-waveplate; QWP, quarter-waveplate.
