The CO2 laser is the standard tool for metal cutting. Particularly in very high power applications, it's much less expensive to build, and where the metal is not perfectly adapted to the CO2 wavelengths, a "helper gas" such as oxygen does the adaptation very well. http://www.synrad.com/fseries/index.htm http://www.hackaday.com/2005/03/27/cut-sheet-metal-with-your-homemade-laser/ http://blog.makezine.com/archive/2005/03/100_watt_metal.html http://www.e-lasercutting.com/ http://news.thomasnet.com/fullstory/27568 http://www.e-lasercutting.com/ John Perry _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
