摘要

We report the preparation and characterization of an attenuated total reflection (ATR) GeO_2 hollow waveguide. An internally GeO_2-coated silica glass tube (bore size 1.0-1.2 mm, length 1.2 m) was prepared using a homogeneous liquid phase deposition method. Kramers-Kronig analysis reveals that the GeO_2 cladding material qualifies as a reflective layer (n_r< 1) for the ATR hollow waveguide structure. ATR-transmission of 9.6-11.7μm light through HE_(11) mode is confirmed by loss spectrum analysis of the sample. The straight and bending (30°) transmission losses for delivery of a ～40 W CO_2 laser beam (10.6μn) are 0.56dB/m and 1.64dB/m, respectively.
