Towards Polish Optical Clock with Cold Strontium Atoms, present status and performance
We report on the status of the work towards cold strontium clock in the Polish National Laboratory of AMO Physics in Torun. The system consists of: (1) a Zeeman slower and magneto-optical traps (at 461 nm and 689 nm), (2) a frequency comb, and (3) a narrow-band laser coupled to an ultra-stable optical cavity. So far, all parts of the experiment are working and the whole system is tested at the 1S0-3P1, 689 nm optical transition in 88Sr atoms with 7 kHz linewidth.
