Not a "laser"
In reply to jrg, Mar 19, 2014

I wouldn't describe light sabers as "lasers".  Laser beams can't just stop three feet from the emitter.  They also can't bounce from other laser beams.

You can't really fence with lasers.  No way to block the oncoming beam.  Also, waving around a powerful laser is insanely dangerous for the one doing the waving.  A 1 watt laser (like the kind they pull out of a projector, mount in a plastic handle and resell for $200 on the 'net), will bounce off a drywall and fry your retinas faster than you can say "The force".
