Paper Abstract

Results of a detailed design study for an advanced optical communication system based on diode-pumped Nd:YAG laser technology performed within the framework of an ESA contract are presented. Emphasis is placed on reaching a low mass/low power design with sufficient maturity to develop space-qualified systems by the middle of this decade. The systems employ coherent PSK homodyne Costas loop receiver technology on the high data rate links, while QPPM modulation and direct detection is foreseen on the 25-Mb/s link. For the intersatellite duplex link, the same communication laser line is used for both directions, thus allowing multiple connections within a given satellite network. With 15-cm aperture telescopes on both terminals, maximum transmitter power is 500 mW for the 650 Mb/s link. Overall communication terminal mass is in the 70-80 kg range, and typical power consumption is 120-160 W.
