Laser frequency stabilization system for the Strontium lattice optical clock

This system stabilizes simultaneously the frequencies of the 689 nm, 813 nm, and 922 nm lasers. The linewidth is narrowed to levels between 100 Hz and 1 MHz, depending on the laser and on the experimental requirements, and the long-term drift is reduced to ca 0.5 Hz/s.

The compensation of the long-term drift is possible using the 698 nm clock laser, which is input into the system in order to determine the drift. It is the compensated by computer control.

The system is completely fiber-coupled and compact.
