- A short description
of the VASAO concept can be found here (pdf).
- New! The provisional error
budget of VASAO (still much to do) is available here (pdf) and an
overview of the challenges is here
(PDF). Both documents are work in progress, and omments, critics, ...
are more than welcome. Send them over the forum or at vasao_cfhtcfht.hawaii.edu.
- New! The paper, controversial
judging by the discussions within ELP-OA, by J.P. Pique et al on "Concept for
polychromatic laser guide stars one-photon excitation of the 4P3/2
level" is here (pdf).
- The SPIE 2006 paper
VASAO by Veillet et al. is here (pdf).
- The 2002 paper by
Schock et al: "Performance analysis of polychromatic laser guide stars
used for wavefront tilt sensing" is here
- The 1995 paper by Foy
et al: "The polychromatic artificial sodium star: A new concept for
correcting the atmospheric tilt" is here (pdf).
- The original modeless
laser developed in Grenoble is described in an article by Pique et al:
" An efficient modeless laser for a mesospheric sodium laserguide star"
published in JOSAB and available here
- A presentation of
ELP-OA made in 2004 by R. Foy is here.
- The modeless laser
built in Grenoble is described on
- ELP-OA is described
on a relatively outdated, but still useful, page located here.
