We present the design, laboratory tests and preliminary field tests of a dynamic refocus system for 351nm Rayleigh beacon laser guide stars. The purpose of dynamic refocus is to increase the beacon signal from a pulsed laser, by maintaining focus in

A cryogenic mechanism has been built to correct for the blurring effects of atmospheric dispersion in adaptive-opticsimages from large aperture telescopes. Steward Observatory's 6.5m telescope features a deformable Cassegrainsecondary mirror compensa

The 22.8 m Large Binocular Telescope Interferometer will be a uniquely powerful tool for imaging and nulling interferometry at thermal infrared wavelengths (2 - 20 micrometers ) because of the LBT's unusual combination of low emissivity, high spatial
