Phasors are a major break-thru in beam weapon technology. They require a very special crystal not found on our world and that cannot be manufactured (yet). By streaming energy through the crystal, a particular type of visible radition is directed as a beam towards a target. The radiation itself contains only sub-atomic particles that have a variety of effects (depeneding on how the energy is projected through the crystal) when it comes into contact with other materials. Phasors are incredibly powerful, deadly beam weapons.
