  We show that with a purely blue-detuned cooling mechanism we can densely load
single neutral atoms into large arrays of shallow optical tweezers. With this
ability, more efficient assembly of larger ordered arrays will be possible -
hence expanding the number of particles available for bottom-up quantum
simulation and computation with atoms. Using Lambda-enhanced grey molasses on
the D1 line of 87Rb, we achieve loading into a single 0.63 mK trap with 89%
probability, and we further extend this loading to 100 atoms at 80%
probability. The loading behavior agrees with a model of consecutive
light-assisted collisions in repulsive molecular states. With simple
rearrangement that only moves rows and columns of a 2D array, we demonstrate
one example of the power of enhanced loading in large arrays.
