Double optical lattices are constructed using four pairs of overlapped laser beams with different frequency. Our optical scheme provides a phase stability between the optical lattices of 5 mrad/s and laser beams with a very clean polarisation state resulting in a power imbalance in the individual laser beams of less than 1%.9 pages, 5 figuresAtomic Physicstext
