Description
We report on the ongoing VLT Laser Guide Star Facility project, which
will allow the ESO UT4 telescope to produce an artificial reference star
for the Adaptive Optics systems NAOS-CONICA and SINFONI. A custom
developed dye laser producing >10W CW at 589nm is installed on-board
of the UT4 telescope, then relayed by means of a single mode optical
fiber behind the secondary mirror, where a 500mm diameter lightweight,
f/1 launch telescope is projecting the laser beam at 90 km altitude. We
described the design tradeoffs and provide some details of the chosen
subsystems. This paper is an update including subsystems results, to be
read together with our previous paper on LGSF design description.
