Featured on the foreground of the telescope is the laser guide star (LGS) clean-room (blue box with white door). The Gemini solid-state sodium laser is located in this box and shines up through a network of tubes and relay optics (also visible) where the beam is "launched" by optics located behind the secondary mirror.
