| Abstract: | We present the experiments on the second-stage cooling for the ytterbium atomic clock. The atoms in the 389.9 nm magneto-optical trap are successfully transferred into the 555.8 nm magneto- optical trap. The temperatures of 174yb and 171yb atomic clouds are about 100 μK and 30 μK respectively, measured by the time-of-flight method. |
