Abstract

This article focuses on precision spectroscopy of the 1S0 (F = 1/2)−4f^13 5d 6s^2 (J = 2, F = 3/2) transition at 431 nm in laser-cooled ^171Yb atoms trapped in an optical lattice. Using an optical frequency divider based on an optical frequency comb, the authors stabilize the 431 nm laser frequency by referencing it to a cavity-stabilized 578 nm laser calibrated to the 1S0−3P0 transition of ^171Yb. They observe a 2.5 kHz linewidth Rabi spectrum and determine the magic wavelength of the optical lattice for this transition to be 797.97(20) nm. The absolute frequency of the 431 nm transition is measured as 695,171,054,856.9(1.1) kHz, with uncertainties dominated by lattice light shifts and statistical noise. These results contribute to the development of optical atomic clocks and precision tests of fundamental physics.
