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...

We have obtained the first measurements with a sodium laser beacon of focus anisoplanatism over large aperture, at the Multiple Mirror Telescope (MMT). Focus anisoplanatism sets the fundamental limit...

THE OPTICS OF THE OWL 100-M ADAPTIVE TELESCOPE (2007)
P. Dierickx, J. Beletic, B. Delabre, M. Ferrari, R. Gilmozzi, N. Hubin
The optical design of the OWL 100-m class visible and near-infrared telescope, with integrated adaptive optics, departs substantially from classical two-mirror solutions. We propose using spherical...
Keck Interferometer observations of classical and weak line T Tauri stars (2005)
Akeson, R. L., Boden, A. F., Monnier, J. D., Millan-Gabet, R., Beichman, C., Beletic, J., ...
We present observations of the T Tauri stars BP Tau, DG Tau, DI Tau, GM Aur, LkCa 15, RW Aur and V830 Tau, using long baseline infrared interferometry at K band (2.2 microns) from the Keck...
The near-infrared size-luminosity relations for Herbig Ae/Be disks (2005)
Monnier, J. D., Millan-Gabet, R., Billmeier, R., Akeson, R., Wallace, D., ...
We report the results of a sensitive K-band survey of Herbig Ae/Be disk sizes using the 85-m baseline Keck Interferometer. Targets were chosen to span the maximum range of stellar properties to probe...
Interferometer Observations of Subparsec-scale Infrared Emission in the Nucleus of NGC 4151 (2003)
Swain, M., Vasisht, G., Akeson, R., Monnier, J., Millan-Gabet, R., Serabyn, E., ...
We report novel, high-angular resolution interferometric measurements that imply the near-infrared nuclear emission in NGC 4151 is unexpectedly compact. We have observed the nucleus of NGC 4151 at...
