Abstract: An apparatus and method for transmission of laser pulses with high output beam quality using large core step-index silica optical fibers having thick cladding, are described. The thick cladding suppresses diffusion of modal power to higher order modes at the core-cladding interface, thereby enabling higher beam quality, M2, than are observed for large core, thin cladding optical fibers.

Output from a 2 m long silica optical fiber having a 100 ?m core and a 660 ?m cladding was found to be close to single mode, with an M2=1.6.
