Abstract

An oscillator–amplifier high-power Nd:YAG laser system was used for transmission of a single 50-ps-long pulse or a train of pulses through a cyclic olefin polymer-coated silver hollow-glass waveguide. The maximum energy that was transmitted was 150 mJ for the train of pulses and 40 mJ for the single pulse, from which followed a delivered power of 100 GW/cm2. The characteristics that were obtained make these waveguides promising for the delivery of high-power laser pulses in medical as well as other applications.
