ABSTRACT:
An N-phase power supply (1) for operation of a laser flashlamp (F). A first electrical circuit (3) is connected between an N-phase source of electrical energy and the flashlamp for continuously supplying electrical current thereto. A second electrical circuit (13) is also interconnected between the source of electrical energy and the flashlamp. This second circuit is for supplying current pulses to the flashlamp. The second circuit includes an N-phase bridge (15) having an electronic switch (17A, 17B, 17C) in each branch (19A, 19B, 19C) of the bridge. An electronic controller (25) controls operation of each switch to produce the current pulses supplied to the flashlamp.
