But that needs air. There's no air in space.

There's an Air and Space Museum

Doesn't need to be air "in space", there just needs to be air somewhere between the laser weapon and whatever it is you don't want the weapon to destroy...

... although it'd probably be easier to use a mirror. Maybe one pointing directly at the person holding a laser weapon. ;-)

Corner reflector. Send it back where it came from, without knowing where they are ahead of time.

Damn... you're right.

Maybe they'll find another way now that they've found one.

A mirror? Light won't reflect off of nothing. The closest you'll get is gravitational lensing, but that requires about a galaxy's worth of mass to make any noticeable difference.
