In the near future, the Gemini Observatory will offer Laser Guide Star Adaptive Optics (LGS AO) observations on both Gemini North and South telescopes. The Gemini North AO system will use a 10W-class sodium laser to produce one laser guide star at Mauna Kea, Hawaii, whereas the Gemini South AO System will use up to five such lasers or a single 50W-class(More)
We describe the adaptive optical (AO) requirements, optical design, and expected performance of a near-infrared AO coronagraph for a 30 meter class giant telescope. The optical design of the instrument consists of back-to-back finite conjugate relays, each containing a collimated space between a pair of toric mirrors. The first collimated space contains the(More)
The Gemini Observatory and University of Hawaii are planning to install an 85-element curvature adaptive optics system with a laser guide star system on its Cerro Pachón telescope in 2001. This paper discusses the motivation, issues on implementing a laser guide star with a curvature-based system, the implementation of a laser guide star based on a(More)
