Sr optical lattice clock optical circuit board, (re)pumping

This optical circuit board combines laser beams at 689nm, 707nm and 679nm into an optical pumping beam. The 689nm beam is frequency shifted by a double-pass AOM. This is one of six optical circuit boards needed to construct a strontium optical lattice clock. These circuit boards transform the laser beams from cw laser sources into the frequency and intensity controlled laser beams that are sent onto the atoms. Please contact us if you are interested in these boards or variations of them, e.g. boards to laser cool other elements than strontium (info@opticsfoundry.com).
