Abstract

Science commissioning of the UnISIS adaptive optics system is underway. In addition to showing test images from this effort, two other optics are discussed. These include a progress report on our continuing effort to improve the UV throughput of the UnISIS laser guide star projection and detection system and our effort to migrate the closed-loop computation engine from OS/2 to real time Linux. The two new improvements to the UV throughput of the laser guide star system involve new high-throughput prisms for the Pockels cell switch and a plan to increase the projected laser energy using anamorphic magnification in the laser beam as it emerges from the Excimer laser.
