Nd:host laser-based optical terminal development study for intersatellite links

A preliminary study to define suitable optical terminals for intersatellite links is presented, and the main configuration tradeoffs are discussed. A modular design approach was pursued, and some innovative technology solutions were traded in order to satisfy the basic requirement of a limited terminal mass. A high-capacity (500 Mbps) return link channel is feasible and fast, and accurate acquisition and tracking operation are achieved.
