Nd:YAG picosecond pulses delivery by cyclic olefin polymer-coated silver hollow glass waveguide

The delivery of short picosecond high-power pulses is highly appreciated in many physical laboratory experiments or in medical and industrial applications. Delivery of high power nanosecond pulses by large core fibers has been already reported, but the picosecond region is still difficult to attain. In our experiment, the delivery of high power and short pulses was proved and pulses with a length of about 50 psec were delivered by specially produced dielectric-coated silver hollow glass waveguides.
