WebThe conceptual scheme of a Sr-based optical lattice clock is the following: cold Sr atoms trapped in an optical lattice are interrogated by a pre-stabilized laser beam (the "local oscillator") on the 1S0 – 3P0 very narrow atomic transition (linewidth < 1 Hz). The laser frequency is then actively kept on the center of the absorption resonance ...
