I'd think a laser powerful enough to melt copper (might need black
anti-reflection coating), would cause charring of the substrate.
If it was powerful enough for a clean cut thru the copper, then
once it does, it will zip thru the fibre-glass before you know
it, making for a rather dandy jigsaw puzzle making kit.
I could be wrong tho.

Maybe you could use the laser to burn off the etch resist coating
around the tracks and pads, then just etch in acid.
