Dumb science question

In science fiction laser/energy weapons are depicted as having no recoil (such as a phaser in Star trek.) Now my question: If humans were to develop energy weapons would they actually be recoil-less or would they have recoil? The reason I'm asking is because physics isn't my strong suit.

  • They mass of the bullet is what causes the recoil. Since the laser has no mass, there will be no recoil. Wouldn't that mean fusion rifles have no recoil then? They look like lasers to me.
