>>> fired a few photons into a vacuum chamber with a cloud of extremely cold rubidium atoms

So it works only in a (sorta) vacuum in the presence of rubidium atoms - so it’s not really a vacuum.

No mention of being able to use it as a weapon.

So it’s an incredibly complicated, impractical flashlight that more than likely requires a huge and probably immobile power supply.

meh. Not a light sabre.

"sabre"I think; I understand what your sayin'..how about a x-ray laser, powered by a high-energy
pulse..say an high-energy capacitor, powered by bleeding off power from engines.
using an high altitude semi-atomious drone on a scram-jet platform?
