Some of you may not be able to access www.laser.org right now. The old server (that hosted this site until yesterday) has taken a turn for the worse. I can't get it to resolve any domain names. However the IP's are still working. You can access the class site temporarily via [removed no longer active]. Please do not add this to your bookmarks as it is a TEMPORARY address and will cease to function in a few days. Sorry for the inconvenience!
