  Advanced quantum technologies, such as quantum simulation, computation, and
metrology are thriving for the implementation of large-scale configurations of
identical quantum systems. Sets of atoms and molecules have the advantage of
having identical intrinsic properties but need to be placed in identical
environments as well. In this work, we present a strong suppression of
dephasing effects and a significant increase of the coherence time for
ensembles of neutral atoms in arrays of optical traps. Compensation of the
differential Stark shift caused by the optical trapping potential is achieved
by the superposition of a second, near resonant light field to the far-detuned
trapping light. The achieved synchronization of the coherent evolution is
demonstrated by analyzing the hyperfine-state phase evolution of atomic
ensembles of $^{85}${Rb} trapped in a two-dimensional array of dipole traps via
Ramsey spectroscopy. The experimental method presented here does not require
the existence of a so called magic wavelength and is expandable to other atomic
species trapped in various dipole trap configurations of arbitrary wavelength.
