Actually an interesting idea. If the Starshot project [1] (which uses ground-based laser propulsion) gets off the ground, perhaps the system could be equally useful for de-orbiting space junk. Firing at orbital objects as they approach from low on the horizon could produce an ablative thrust that could accelerate the natural de-orbiting process.
