Abstract

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