Fabrication of Low-Loss AgI/Ag Hollow Fibers for Laser Light Delivery in the Near Infrared Region
AgI/Ag hollow fibers have been fabricated and found applications in mid-infrared wavelength regions. However, it is a challenge to fabricate low-loss AgI/Ag hollow fiber in the near infrared region, because it is difficult to control the film thickness and surface roughness. Some improvements, including ethanol as the new iodine solvent, low iodination temperature, and fast flowing rate for the iodine solution with a vacuum pump, are proposed in order to coat a thin and smooth AgI film with a thickness of 70 nm. Low-loss AgI/Ag hollow fibers with various inner diameters are obtained for 1 μm wavelength band. The measured transmission loss is 1.15 dB/m for the 1.064 μm diode pumped solid state laser system. Fabrication parameters including iodine concentration and reaction temperature are discussed in detail. The transmission and bending loss properties of the AgI/Ag hollow fibers with various inner diameters in the near infrared region are evaluated.
