Abstract
Coherent Technologies, Inc. (CTI) is developing the first commercial solid-state sodium beacon laser guidestar (LGS): a critical step towards addressing the need of the astronomy adaptive optics (AO) community for a robust turn-key commercial LGS that can be upgraded for different observatory facilities and for different AO formats - including multi-conjugate AO (MCAO) and future extra-large telescopes. The LGS that is currently being developed will be a 14 W single beacon system to be installed on the center section of the Gemini North telescope in Fall 2004. This paper describes the Gemini North LGS requirements, the design of the laser with design trades against other LGS architectures; the functionality of the automated remote laser control system; latest size, weight, power, and performance data; and the current status of the program.
