A 5W laser can't cut steel. You need to be in the kilowatts before you can cut metal (unless it is very very very thin).


You may well be correct, and I spoke out of turn, but it is my understanding that the wavelength of the laser can make a huge difference.


Club show lasers of 5W are pretty common.


I'm sorry, but there's no way around it, with 5W you can cut metal just as easily as you can cut a tree with a knife. At least with contemporary technology (In the future who knows).
