High-Power Nd:YAG Laser Beam Delivery by Optical Fiber

Abstract

The advantages of using fiber beam delivery for high-power Nd:YAG lasers were well known. In many cases, high-power YAG laser was one kind of multimode laser, its beam quality was evaluated by beam parameter product ω θ . At a given output power, the laser beam parameter product was a constant, which is only related to laser resonator structure.
