Measurements on commercially available fused silica fibers and fiber tapers have shown that Nd:glass laser pulses of irradiance {gt}3.5 GW cm{sup {minus}2} can be transmitted without bulk or surface damage. Optical energy at the fiber output can be used for efficient acceleration of thin metal foils. For 0.025-mm-thick aluminum coupled to a 0.2-mm-diam fiber, target foil velocities up to 2.3 km s{sup {minus}1} have been achieved with very modest laser energies ({lt}25 mJ).
