I’ve heard that some users have been leaving the room unattended while the laser is running. This is NOT PERMITTED. No matter how safe you think the job is, Colaser safety policy requires you to remain in the room whenever the laser is running. If you are forced to leave the room for any reason, you must pause or cancel the job before you do.

If you feel unable to comply with this safety policy, please don’t use the laser.

You may have noticed that Volume 2 of the paper log book has been losing its pages. My mistake for buying a notebook with tear-out pages! I’ve gathered up all the loose pages and sorted them into chronological order as best I could, and scanned both volumes into PDF files. Those files are now available for reference here in the Download section of the web site.

There is a third paper volume (hardcover, with pages that don’t tear out) in the laser room now. Please continue to log your work in the paper log book.
