Agenda

= = > Workshop AGENDA (pdf)

The CfAO Fall Retreat this year will be taking place at Lake Arrowhead. As part of this retreat, one day (Friday Nov 2) will be dedicated to a third "Laser Technology and Systems for Astronomy" workshop. The purpose of the workshops is to foster information interchange between laser users and laser developers, discuss the challenging problems or limitations in laser performance, and create potential collaborations for CfAO research efforts in the remaining two years of the Center. Agenda topics might include

1. Status of the telescope LGS AO projects. 2nd generation laser requirements.
2. Sodium return signal measurements. Quantitative methods for characterizing the outgoing beam quality, spot size, and return signal, Laser to sodium coupling physics.
3. Key component technologies status (mixing crystals, fibers).
4. Methods of beam transport, projection, and uplink correction.
5. Lessons learned in field hardening for mountaintop operation.
6. Strategies for making the laser technology available to the astronomical community.

I welcome your ideas and suggestions! This is a follow-up to our November 2006 Sodium Laser Guidestar Workshop and March 2007 Sodium Laser Guidestar Workshop, 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.)

As advance of the workshop, please send me or upload copies of your presentations that you are willing to share with your fellow colleagues. These should be prepared for general release to the public, since they will be posted to the workshop page. You might notice that I made an attempt to find the latest available reports and publications and put links to them in the tables on the SodiumLaserGuidestars page.
