Sr optical lattice clock optical circuit board, 689 nm

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. On this board a 689-nm laser beam originating from the fibre coupler on the right is split into two beams using a half-wave plate (black ring) and a polarizing beam splitter cube. Each beam is frequency shifted and intensity controlled by an AOM (metallic box, mounted with warm side away from glass bench). One beam also passes an EOM (black box). Both beams are sent onwards through optical fibres. 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).
