Emitter matrix

The emitter matrix, also referred to as a high energy flux aperture was a crucial component of the lightsaber. A saber's blade was emitted out the handle through the emitter matrix which kept a tight magnetic grip on the beam and allowed it to reliably extend to a predetermined length. A lightsaber would explode shortly after ignition if the emitter matrix was inverted - a tactic used once by Petro, a Jedi initiate, to subdue a group of pirates.
