Research output: Contribution to journalConference articlepeer-review


Hollow plastic tubes covered inside with films of metal or metal and dielectric materials were shown to transmit CO2 laser light with high yields. There was only a small influence on the transmission of light by the radius of curvature on the tubes or the input energies. Output energy intensity measurements have shown that, under certain conditions, whispering gallery modes could exist inside the fiber, which gives low attenuation and negligible variations of transmission with bending. This makes this type of fibers suitable for medical applications especially in surgery.
