Antiphoton pulse
From Memory Alpha, the free Star Trek reference
An antiphoton pulse was a type of deflector pulse emitted on a triaxilating frequency bandwidth.
Unlike a photonic disruptor, the antiphoton pulse would only shut down any heavily armoured holo-emitter without damaging the program it was projecting. Emitters could still be protected from the pulse using deflector shields, or by emitting a feedback surge on the inverse triaxilating frequency to counter the pulse.
In 2377, B'Elanna Torres reconfigured the deflector dish of the USS Voyager to emit an antiphoton pulse against Iden's starship. The pulses are only effective against an unshielded target. The pulse was counteracted by reconfiguring the Hirogen tracking beam to generate the feedback surge. (VOY: "Flesh and Blood", "Body and Soul")
