As for UV or IR lasers, how would you aim them?

Possibly by "piggybacking" them to one of your "toy" lasers such that both
hit the same spot.

And there you go. We have gone from a claim that laser pointers can cause
retinal damage of pilots in aircraft several thousand feet distant, and
bring down airliners in the process, to a claim that laser pointers can be
used as sighting devices for a CO2 or other high power laser with an
invisible beam. Why would you give yourself away with a visible beam when
you can use a high powered optical sight? You don't have windage or gravity
to deal with. Should we mitigate the risk posed by high power invisible
laser beams? How should we mitigate the risk?
