You can get a powerful enough laser diode off eBay. Been wanting to play with them for a while. I'd go for the water-cooled type. The power supply has to send a pulse to the laser, then measure the internal resistance to determine how hot the thing is and use that info to fire the next pulse. Pulse width is in the millisecond range from what I've read.
Here is a 35W laser diode for $150: http://cgi.ebay.com/Coherent-35-Watt-800-810nM-Laser-Diode_W0QQitemZ130286842046QQihZ003QQcategoryZ53141QQssPageNameZWDVWQQrdZ1QQcmdZViewItem I don't see any currently, but ones designed for cutting come up now and then. -Dave Walton On Fri, Feb 13, 2009 at 1:39 PM, Wilton Strickland <[email protected]> wrote: > 'Talking to engineer/inventor friend again at lunch today.
