can some kind of high-powered light beam offer a means of propulsion?

The fundamental question I’m trying to ask is, can some kind of high-powered light beam offer a means of propulsion?Let’s say you have a twelve-pound probe with a light source as an engine, and a near infinite amount of energy to power it.If this light emitting engine could be illuminated to be as bright as the combined omni-directional light of a star – or perhaps a supernova – and focused into a very finite stream of photons like an extremely high-powered laser, would your probe accelerate in the opposite direction than the beam is being emitted from in relation to an object that was once moving through space at the same velocity as your probe?
