	The enabling point of a practical, low-cost laser design is the ability to do significant cuts (1/8") by performing multiple passes over the cut pattern. If each cut does [http://www.nelaser.com/deep_engraving.html 10 thousandths] of an inch in steel for an 80 watt laser - then 12 passes give you a 1/8" cut. This is sufficient, for example, to laser-cut a 20" [[Sawmill]] blade		The enabling point of a practical, low-cost laser design is the ability to do significant cuts (1/8") by performing multiple passes over the cut pattern.

			Bart Dring of BuildLog drew my attention to this: According to [http://www.instructables.com/id/CO2-laser-that-cuts-sheet-metal/step4/Laser-Optics/ this], you need 106 watts per square inch (1.55kW/mm<sup>2</sup>) to cut metal. A 100W laser with a 280 micron diameter dot will cut metal. We would be looking for more precision than that anyway, perhaps 100 micron diameter, so 100W or less should suffice. Wavelength is more of an issue than power; metal acts like a mirror to a laser in the infrared spectrum.
