Paper Abstract
ARGOS is an innovative multi-star adaptive optics system being built for use with LUCIFER on the Large Binocular
Telescope (LBT). LUCIFER is a wide field imager and multi-object spectrograph. Using a constellation of laser guide
stars permits PSF correction over a wide field in exchange for a relatively small sacrifice in achievable correction. The
laser constellation consists of three stars per each of the two eyes of the LBT. The stars are nominally positioned on a circle
2' in radius, but each star can be moved by upto 0.5' in any direction. Nd:YAG (SHG) lasers from InnoLas Laser GmbH
are used to create the green (532nm) laser stars, and have an output above 18 W each at the planned pulsing frequency of
10kHz. The lasers are launched using a 40cm telescope and focused at a height of 12 km. The laser system is designed
to be optically simple yet configurable. It also provisions for a central sodium laser to be installed later. We detail the
characteristics of the laser system and the current state of its development.
