A DVD laser is IR and a CD laser is red. Would the optics from the lasers
work for UV?

I presume a CD or DVD burner has all the optics required to focus the laser
diode to a very tiny spot. Maybe it's just a matter of swapping out the
diode for an ultra-violet version. Also concerning not being able to see it;
I know the coating inside fluorescent tubes converts a lot of ultra-violet
to visible light. Maybe a target made form a piece of coated glass could be
made to "see" the dot at least long enough to focus it if required.
