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.

  • You're creating an object/mass/force, not expelling it. Expelling something takes effort and thrust while creating something (like a laser from photons) it requires no thrust.
