A fabrication condition has been newly established to transmit pilot beams in cyclic olefin polymer-coated silver (COP/Ag) hollow fibers for CO2 laser light. The COP/Ag hollow fibers show low loss properties in the visible wavelength band of 0.5-0.7 μm without affecting the loss of CO2 laser light significantly. Bending losses of visible light with the wavelengths of 0.63 μm (red) and 0.53 μm (green) are evaluated. It is shown that both the red and green pilot beams are successfully delivered with low losses even when the fibers are bent to the angle of 360 degrees.
