Phasers are plasma and other stuff?

[Lucky]

SHELBY: I think we should look at modifying the plasma phaser design.

LAFORGE: At the same time, we'll be retuning phasers to higher EM base emitting frequencies to try to disrupt their subspace field.

SHELBY: Time index five one four. Data started to fluctuate phaser resonance frequencies. The Borg's beam breaks contact. Slow playback. Take a closer look, Commander. Mister La Forge?

PICARD: No signs of phaser burns on the hull. 
LAFORGE: No, sir. Torsional stress levels point to a disrupter-style weapon.

WORF: These wounds were caused by a forced plasma beam, similar to a Ferengi hand phaser.
