Resonance pulse

From Memory Alpha, the free Star Trek reference

A resonance pulse is a type of energy.

After the USS Voyager was duplicated by a subspace divergence field in 2372, the two ships attempted to merge again by re-creating the field and then depolarizing it, using a massive resonance pulse generated simultaneously from the main deflectors of both ships. However, the attempt had to be aborted as the fields were too chaotic for a merging to be possible. (VOY: "Deadlock")

In 2376, a Turei starship targeted the USS Voyager's shields with a resonance pulse, which altered their shield harmonics and pushed them out of the Underspace. (VOY: "Dragon's Teeth")

In 2378, two Hierarchy renegades extorted the the Doctor into disguising himself as Captain Kathryn Janeway and stealing Voyager's warp core. As Janeway, the Doctor asked B'Elanna Torres whether there was a way to tractor the core safely at warp. Torres replied that she could modify the tractor beam emitters to emit a resonance pulse that would stabilize the core's containment field. (VOY: "Renaissance Man")
