Anti-photon pulse
An anti-photon pulse was a type of energy discharge which could be used to disrupt a photonic lifeform.

In 2377,  chief engineer B'Elanna Torres conceived the idea of reconfiguring the ship's deflector dish to emit an anti-photon pulse on a triaxilating bandwidth, in order to deactivate the holo-emitter being used by Iden and his holographic crew.

After two hours of modifications, Torres was able to fire the pulse at Iden's ship, but Iden was able to counter the attack by reconfiguring the ship's tracking beam to the inverse frequency of the pulse. This created a feedback surge in the pulse which nearly caused Voyager to experience a warp core breach. ()
