    "abstract": "We study the scintillation index of N partially overlapping collimated lowest\norder Gaussian laser beams with different wavelengths in weak atmospheric\nturbulence. Using the Rytov approximation we calculate the initial beam\nseparation that minimizes the longitudinal scintillation. Further reduction of\nthe longitudinal scintillation is obtained by optimizing with respect to both\nbeam separation and spot size. The longitudinal scintillation of the optimal\nN-beam configurations is inversely proportional to N, resulting in a 92%\nreduction for a 9-beam system compared with the single beam value. The radial\nscintillation values for the optimal N-beam configurations are significantly\nsmaller than the corresponding single beam values.",
