| Abstract: | The Strontium cooling experiment realized to transfer atoms from the first stage broadband cooling to the second stage narrow line cooling. The temperature of the atoms after the second stage cool- ing is about 2 μK. The lattice laser is on during the cooling process, so the atoms are loaded into the lat- tice when their temperature is low enough, cooled by narrow line cooling. |
