Abstract

The Laser Guide Star Facility (LGSF) system of the Thirty Meter Telescope (TMT) will generate up to 8 artificial laser guide stars in the mesospheric sodium layer with the brightness, beam quality, and asterism geometries as required by both the TMT first light AO system and future AO instruments. It includes the sodium lasers mounted on the telescope elevation structure below the primary mirror, the conventional beam transfer optics system to transport the beams up to the telescope top end, and the formatting and launching optics to project the required laser guide star asterism to the sky using a center launch telescope located behind the secondary mirror. In this paper, we will present the recent successful completion of the LGSF preliminary design, including: the optical, mechanical, electronics, safety, control, and software designs; the systems engineering; the modeling activities; and the next steps for the system’s final design phase including prototyping.
