Abstract :
We developed an 171Yb optical lattice clock and measured the absolute frequency of the optical clock transition 1S0 (F = 1/2) - 3P0 (F = 1/2). The frequency was determined at 518 295 836 590 865.7 (9.2). The uncertainty is equivalent to 1.8×10-14 relatively. The magic wavelength of lattice laser was founded at 394 798.18(79) Hz.
