5th Laser Technology and Systems for Astronomy Workshop, November 8-9, 2009

arrowbleft Fall 2008 Workshop


This year the Center for Adaptive Optics will once again be hosting a two-day workshop on Laser Technology and Systems for Astronomy. The purpose of these workshops is to foster information interchange between astronomy uses laser system developers, and scientists studying the interaction of the mesospheric sodium with laser light. We will discuss our experience, perceived challenges and future potentials in improving sodium laser guidestar performance and use this meeting opportunity to exchange ideas and develop collaborations.

Technical topics might include

  • Status of the telescope LGS AO projects. 2nd generation laser requirements.
  • Modeling the laser to sodium coupling physics and return signal.
  • Sodium return signal measurements.
  • Key component technologies status (mixing crystals, fibers).
  • Methods of beam transport, projection, and uplink correction.
  • Lessons learned in field hardening for mountaintop operation.
  • Strategies for making the laser technology available to the astronomical community.

I welcome your ideas and suggestions! This is a follow-up to our earlier workshops in November 2006, March 2007, November 2007, and November 2008 at which we heard about some of the latest cutting edge developments.

On the Interactive web pages on Sodium Laser Guidestar research web page you will find: … table of lasers on-sky and reported characteristics … table of ongoing laser development projects … list of past and upcoming meetings … people contact list … blog area for commentary. The web pages are editable by everyone, just like “Wikipedia” pages. (To start editing or make entries to the blog, you just need to register, which is quick and easy. But you can peruse the pages without registering.)




The workshop will be held in conjunction with the Center for Adaptive Optics Fall Retreat at the UCLA Lake Arrowhead Conference Center in Southern California. The Fall Retreat starts Thursday November 5 and lasts until Sunday November 8. The Laser Workshop will start out as a breakout session of the Retreat starting the morning of Sunday November 8 and will last through the end of the day on Monday November 9. Attendees of the workshop will be able to spend the extra night (Sunday) at the UCLA conference center and meals will be provided. The CfAO will be opening up registration in early September. Workshop attendees should register for the Retreat and check the "Attending Laser Workshop" box.
