Well, then I suggest you go back to
wherever it was you saw this laser and find
out EXACTLY what it was. Efficient metal
cutting requires a nice gaussian beam. That
means either CO2, DPSS, or fiber coupled.
20 gauge is only 36mils, so it is very thin
meet shetal. Think of a computer case.

Etching metal is an entirely different
ballgame. It works by blasting away the
surface. An 8W diode isn't going to "cut it".

15W Co2 CW will melt thin iron wire like the supports in filaments lamps when focused but thats very thin

60W from a 808nm diode when focused can burn holes into craft knife blades and I managed to ignite magnesium with 60W of Co2 power both focused and unfocused , not cut unfortunately :P
