The flexible hollow waveguides - a cyclic olefin polymer-coated silver hollow glass waveguides (COP/Ag) with various inner diameters (540 μm, 700 μm, and 1000 μm) - specially prepared for the delivery of high power 1.06 μm radiation were investigated using an oscillator-3 amplifiers Nd:YAG laser system. The length of a single pulse was equal to 50 psec. In dependence to a diameter of the waveguide, transmission/attenuation as a function of the input laser energy were measured together with the input/output time radiation characteristics (in a picosecond resolution) and the spatial distribution of the output beam. The input energy up to 80 mJ, 70 mJ, and 30 mJ was transmitted with an efficiency higher than 90% for the COP/Ag hollow waveguides with a diameter of 1000 μm, 700 μm, and 540 μm, respectively. The picosecond temporal measurements show that the delivered pulse duration was not changed within a resolution of 5 picosecond. Therefore the maximum transmitted power reached was 1.5 GW. The characteristics obtained make all these waveguides very promising for the delivery of high-power laser pulses in special medical and other applications.
