Abstract

The radiation pattern of a collimated diode laser that was used to transmit messages between two points far apart is considered as a function of a driving current, pulse repetition rate, and relative humidity along the propagation path. It is shown that the spatial and energy distribution characteristics of the laser beam projected over long distances are affected by the humidity and temperature conditions of the atmosphere.
