Optimization of safe free-space optical link

Original language description

This paper describes an optimization of a safe laser free-space optical link. Safe link is a link with zero nominal ocular hazard distance. This requirement can be met only if the transmitted power of the optical signal is at its maximum permissible value, which is defined by the maximum permissible exposure and by the diameter of the transmitter output aperture. This rule also applies to reaching maximum link range, maximum link margin, or maximum beam angular deflection limit. Then, the safe transmitted optical power, the link margin, and the beam angular deflection limit represent limiting factors of the optimization. Two optimization tasks were analyzed. First task searched for a maximum link range; the link range equation represented the objective function. In the second task, the link resistance to the atmospheric attenuation and spatial fluctuations of the optical beam were maximized for the given link. Either the link margin or the beam angular deflection limit were used as the objective functions. In all cases, the aim of the optimization process was to find the optimal laser beam divergence. It was a divergence when the appropriate objective function reached the maximum for given parameters of the link and atmosphere. The single input single output link was considered.
