Setup of 767 nm reference laser. Schematic representation of the optical circuit of the reference laser. Labels: M mirror, L lens, K potassium, HWP half-wave plate, QWP quarter wave plate, PBS1, PBS2, PBS3, PBS4 are polarizing beam splitters, AOM acoustic-optic modulator, EOM1 fiber electro-optic modulator, EOM2 free space electro-optic modulator. The output of DL 100 is passed through a combination of AOM and fiber-based EOM to obtain the desired shift in the frequency. Before the output is taken to the experimental table, it is passed through a free-space EOM to create sidebands for PDH locking
