Abstract :
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.
