The Office of Naval Research successfully disables a small target vessel using a solid-state, high-energy laser mounted onto the deck of the Navy's self-defense test ship, former USS Paul Foster (DD 964).Fibre lasers were invented in 1963, and since the 1990s they have been advanced almost entirely by IPG Photonics in Oxford, Massachusetts. Whereas other solid-state lasers use rigid rods, slabs or discs of crystal to generate the beam, and so have to be fairly large, fibre lasers use thin
