In this paper beam propagation analysis of a multi-beam multi-collimator optical communication system through free space is studied. For this purpose, the propagation properties of Gaussian multi-beams through a multi-optical path including collimators in transmitters are studied and an analytical formula for intensity distribution is derived. The effects of beam divergence and beam separation distances on the propagation properties of Gaussian multi-beams are studied in detail by calculating the beam width and power in bucket (PIB). The analyses are illustrated by numerical examples.
