N2 - The attenuated total reflectance (ATR) hollow waveguides capable of transmitting CO 2 laser have attracted wide research interest due to its advantages of simple structure, no end reflection, small beam divergence and good transmission modes. In this work, GeO 2 ATR hollow waveguides for delivery of CO 2 laser radiations were fabricated via an acid-induced liquid phase deposition (LPD) process. GeO 2 hollow waveguide samples were deposited from acidic aqueous germanate ion solutions with different GeO 2 concentrations. The morphology, compactness and surface roughness of the LPD-derived GeO 2 ceramic film were examined by SEM. The crystalline structure of the film sample was determined using XRD. The low-loss window of the GeO 2 waveguide tube was observed by a FTIR spectrometer. We measured the transmission loss of the sample for delivery of a 10.6 μm TEM 00 CO 2 laser beam. The results show that the variations in loss are consistent with the quality change of the GeO 2 ceramic films grown in solutions at different concentrations.
