Lasersaur. Lasersaur The Lasersaur is an open source laser cutter.
We designed it to fill the need of makers, artist and scientist who wanted a safe and highly-capable machine. Unlike others it comes fully loaded with knowledge to run, maintain, and modify. Since its conception, Nortd Labs and the Lasersaur community has generated knowledge to develop a comprehensive system. We have specifically focused on laser cutting, software, and making the building process repeatable.
How can you Contribute? Unlike software, hardware RD is costly even when living off of Ramen.

Class 4 Burning, Cutting Lasers. Note: This tube is included in the LABURN20 kit and assembled laser, so you do not need to purchase it separately if you are buying the LABURN20 or 2K.
But it's also available here separately if you need just the tube itself, for building your own design or as a replacement. High efficiency laser diodes can produce up to 2 watts at wavelengths of .6 to over 1 micron, multi or single mode. The carbon dioxide experimental laser is built from readily available parts and pieces. System advantages are low cost and versatility. Power output is in excess of 25+ continous watts @ 10.6 microns multimode when properly setup. System is classified as a class 4 laser product and is labelled accordingly with all the necessary compliances as dictated by the NCDRH. System is an axial flow water cooled design with external fittings for experimental gas mixtures.
Output is more than sufficient for wood engraving, plastic and textile cutting as well as materials research. Great Advanced Science Project! CNCzone.com-Machinist Community Forums - Welcome Page.

Other Examples of Home-Built N2 Lasers Well, this one probably wasn't actually built at a home but close enough. :) The following is from a paper by Bruno Godard entitled: "A Very Simple High Power Large Efficiency N2 Laser", May 1973. The copy I have is from the "Laboratoires De Marcoussis, Centre De Recherches De La Compagnie Generale d'Electricit, Departement Recherches Physiques de Base, Section Sources d'Ondes Cohrentes", 91460 - Marcoussis France. Thanks to Jon Singer ( jon@joss.com ) for locating this paper.
Note that I don't know of anyone duplicating these results. Notable physical features of this design include: A parabolic shape for the primary capacitor electrode (the one with the spark gap) to create a linear excitation of the laser channel that moves with the speed of light. A longer cavity than that of the SciAm laser (almost double). (From: Jon Singer, of the Joss Research Institute.) Overall - M. Power supply - L.
