This brings to mind the Royal Institution Christmas Lectures which occur every
year here in the U.K., and which this year were about "Crystals and Lasers".
One gadget which the lecturer showed off was a small CO2 laser from China. It
had enough power to put a hole in a piece of paper at a range of about 2-3 ft.
It was contained in a black box with pretty dragon pictures on it - and the
box was about the size of a cigarette case! It was battery powered. Would this
do the job?

I've also seen a battery powered laser sight for use on rifles advertised. It
is not powerful, and the spot can only be seen in low light conditions, but
the sight is on the open market now.
