✦ Synopsis
A new kind of cyclic ole®n polymer COP-E48R has been selected as the dielectric material for a silver hollow glass tube. Owing to its lower extinction coecient at the wavelength of 10.6 mm, transmission losses for the CO 2 laser light has been reduced signi®cantly in the COP-E48R-coated silver (COP-E48R/Ag) hollow glass waveguide. By properly selecting the ®lm thickness of COP, Er:YAG and CO 2 laser light are shown to be transmitted with low loss simultaneously or independently. Delivery properties of red and green pilot beams were also evaluated.
