Sr Optical Lattice Clock Assisted by Optical Frequency Combs for Contribution to International Atomic Time
We evaluate the uncertainty of our Sr optical lattice clock at the 10−17 level, through robust clock operation with assistance of optical frequency combs. This clock will be operated for contribution to the International Atomic Time.
