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.

No because light does not have mass therefor no recoil is produced on a laser actuated weapon but a plasma rifle or some sort will because plasma does contain mass.
