Compact optical lattice clock with a volume of 250 L (IMAGE)
Caption
A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, lasers for manipulating atoms, a control system for clock operation, and an optical cavity that serves as a frequency reference for the lasers. Laser-cooled atoms are trapped in the optical lattice, and the clock transition frequency is measured with high precision in a low-temperature blackbody radiation shield.
