If you look at CO2 lasers, at 40W ($350 on eBay) you can cut plywood, at 150W ($5000 on eBay) you can cut metal. Both of those are 1040 nm. The 450 nm modules

If you look at CO2 lasers, at 40W ($350 on eBay) you can cut plywood, at 150W ($5000 on eBay) you can cut metal. Both of those are 1040 nm.
The 450 nm modules you can get up to 5W ($100 on eBay), but those can hardly cut anything, they're more like engravers.
