Abstract

A single-conjugate adaptive optics (AO) system for the 6.5 m MMT based on an adaptive secondary mirror is now undergoing commissioning at the telescope. In addition to providing the basis for a program of scientific observations, the system will serve as a platform for the development of a dual-conjugate AO system in which a constellation of five refocused Rayleigh laser guide stars (RLGS) will provide the majority of the wavefront information. A SCIDAR campaign at a telescope close to the MMT site is beginning to generate explicit measurements of the atmospheric turbulence profile. In this paper, we describe the current system design, and present the results of initial performance simulations using the measured atmospheric parameters.
