[jnlqpgus] Non-dissipating beam

Imagine a beam of a peculiar kind of energy that bends space around it (kind of like a gravitational lens) so that the beam remain tightly focused forever as it travels through vacuum.  The motivation is intergalactic communication, assuming you can aim the thing properly.  Or a weapon.

I can't decide whether this is science or science fiction.  Self-focusing does seem to occur in materials, but it doesn't seem applicable to long range communication.
