Sr optical lattice clock optical circuit board, 813nm lattice

This optical circuit board prepares a laser beam for the magic wavelength optical lattice. The input laser beam is  filtered by a bandpass filter and a volume Bragg grating, intensity controlled by an AOM and modulated by an EOM. A 698-nm clock laser beam for coarse spectroscopy is coupled with the 813-nm lattice light into the output fibre. This is one of six optical circuit boards needed to construct a strontium optical lattice clock. 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).
