The Galileo Optical Experiment (GOPEX) has demonstrated the first laser communications uplink to a deep space vehicle. The optical design and validation tests performed at the Table Mountain Facility (TMF) transmitter site are described. The system used a 0.6-m telescope and an optical system at coude focus to produce the uplink beam. The optical system used a pulsed neodymium:yttrium-aluminum-garnet (Nd:Yag) laser and beam diverger optics to produce the required optical output. In order to validate the optical design, a number of uplinks were performed on Earth-orbiting satellites (e.g., Lageos 1 and 2).
