I'd start thinking around 1000 Watts, very generally. Aluminum
is pretty reflective down into the IR wavelengths, and is one of
the best heat conductors. That makes it hard to weld, too.
So, aluminum and copper are a BEAR to cut with laser. It might
be possible to improve the reflection situation with a dark coating
on the face of the aluminum.
