I can't remember where I read it but something that bends into this territory is a "blaster shot" of laser/plasma. Scientists have recently figured out/tested a way to fire a burst of light and have wavelength and refraction interplay and create a self-reinforcing bolt like a vortex ring. Damage dealt by the laser weapon would be in the form of plasma.
Edit: I didn't find the paper but i did find the name of the relevant effects, Self-focusing and filament propagation. Related to piping laser over distances is this paper.
