A 0.5 W beam from a continuous-wave dye laser, tuned to the D 2 resonance of atomic sodium, has been used to generate an artificial guide star by illuminating the mesospheric sodium layer, 90 km...
Optical Sciences Center and (2007)
J. H. Burge, E. Sabatke, N. J. Woolf, Steward Observatory
Increased performance for optical telescopes has historically come from larger apertures, from technological advances for the telescope components, such as detectors, and from access to better sites,...

this report is the outcome of over almost two decades of discussions within the scientific community and with various space agencies, as described in the COMPLEX, TOPS, Darwin and ExNPS reports. TPF...
Results From The Ncc/nicmos Spare-Detector June 2000 Emi Test (2000)
Report To Nasa, Glenn Schneider, Steward Observatory
this report, other than a first quick-look at the asynchronouly sampled data, we discuss only the results derived from the 26-read 1.2-second deltatime multiaccums
