This should be useful to you. Take especial note of the method of bombarding afoil with a femotsecond pulse beam to emit relativistic ions. Granted, not sure if that would work with beam propulsion from a remote source (you could bounce the pulse off a mirror to strike the foil from the correct direction, I suppose.

To give you my two cents, this seems totally possible with beamed power from a ground or orbital station. The question is, what size is the vehicle, and at what point, given vehicle mass considerations, would you want to use a laser sail rather than a laser ablation engine.
