Abstract

The optimum diameter of a circular beam of collimated optical radiation normally incident on the ocean surface, in order to obtain a maximum time-average power density vertically downward, is determined for (1) the case of a given constant beam power density and (2) the case of a given constant total beam power. The resulting optima are functions of the roughness of the ocean surface (wind velocity), the depth of the point of observation, and the index of refraction.
