摘要	At present the optical clock with accuracy and stability achieves to 10(-18) level, which could be the next generation of time and frequency standard. This paper gives an introduction of the progress of researching on the optical lattice clock of Strontium atom in NTSC (National Time Service Center). We realize the (5s5s)S-1(0)-(5s5p)P-1(1) cooling (blue MOT) and (5s5s)S-1(0)-(5s5p)P-3(1) cooling (red MOT) in succession for the optical lattice clock, and loading these cold atoms in a lattice composed by a magic wave-length is studied. By using our narrow line-width diode laser and the fiber femtosecond optical frequency comb, we precisely measure the absolute frequencies of the inter-combination transitions (5s5s)S-1(0)-(5s5p)P-3(1) of four isotopes of Strontium referenced to an H maser.
