Calculation of Power-Generating Parameters of Laser Radiators for Satellite-to-Satellite Optical Communication Links and Earth-to-Satellite-to-Earth Links

Results are given of calculations of required power-generating parameters of laser radiators for the apparatus of satellite-to-satellite communication links versus the satellite-to-satellite distance and the antenna diameter and also the same for the apparatus of the ground-based experiment Earth-Satellite Angle Reflector - Earth. For the satellite-to-satellite communication links the power-generating parameters were calculated for the typical diameters of reduced-weight antennae of 20-40 cm and for satellite-to-satellite distances up to 80,000 km. The calculations of power-generating parameters, conducted for the ground-based experiment, revealed the possibility to decrease the transmitter power when using an astronomic telescope with a large aperture diameter (1,2 m) as a receiving antenna.
