Abstract

Cyclic olefin polymer-coated silver hollow glass waveguides with inner diameters of 540 μm, 700 μm, and 1000 μm were used for transmission of single pulses in picosecond region generated by a high-power Nd:YAG laser system (wavelengths 1.06 μm-first (fundamental) harmonic and 0.53 μm-second harmonic). Maximum first and second harmonic intensities delivered by 1000 μm inner diameter waveguide were 185 GW/cm2 and 48 GW/cm2, respectively. For fundamental radiation guided by the waveguide with the inner diameters 540 μm, and 700 μm the maximum measured transmitted intensities were 397 GW/cm2 and 331 GW/cm2, respectively. Temporal development with picosecond resolution, spatial profile, and divergence of delivered laser pulses were determined for each waveguide.
