Paper Abstract
A multi-laser adaptive optics system, at the 6.5 m MMT telescope, has been undergoing commissioning in
preparation for wide-field, partially corrected as well as narrow-field, diffraction limited science observations in
the thermal and near infrared. After several delays due to bad weather, we have successfully closed the full high
order ground-layer adaptive optics (GLAO) control loop for the first time in February 2008 using five Rayleigh
laser guide stars and a single tilt star. Characterization and automated correction of static aberrations such
as non-common path errors were addressed in May 2008. Calibration measurements in preparation for laser
tomography adaptive optics (LTAO) operation are planned for the fall of 2008 along with the start of shared-risk
GLAO science observations.
We present the results of GLAO observations with the PISCES imager, a 1 - 2.5 &mgr;m camera with a field of
view of 110 arc seconds. The status of the remaining GLAO commissioning work is also reviewed. Finally, we
present plans for commissioning work to implement the LTAO operating mode of the system.
