The aim of this paper is to investigate the transmission properties of hollow waveguides for the case when high-quality carbon dioxide laser beams are launched efficiently at the input. It has been found that the output intensity profile from a hollow waveguide when a high quality input is provided, depends on the number of modes in the output beam as well as on the relative phase difference among the modes. Thus the output intensity profile normally consists of multiple peaks and throughs, reflecting the fact that the mode structure of the output beam is mainly determined by the launching conditions and any bending of the fiber.
