Phase cannon

Phase cannons were a type of phased energy weapon used by the United Earth Starfleet during the mid 22nd century. They were the precursors to Phasers, which would be widely used from the 23rd century onwards. 

An advanced version of the Phase cannon was used by the USS Enterprise in the 23rd century of the alternate reality started by Nero. While the ship was also equipped with Phasers, the phase cannon served as a devastating weapon, capable of blasting through multiple ships at once.
