Polystyrene-coated hollow glass waveguides were fabricated by means of liquid phase deposition method. The length of the waveguide is about 1m and its diameter is 800 to 1200μm. The minimum optical loss of the waveguides is 1.73dB/m with damage threshold higher than 11.2W (17.2W/mm²) for CO₂ laser (10.6μm). Experimental results show that polystyrene-coated silver hollow glass waveguides are suitable for delivery of CO₂ laser in medical applications, and are also promising for energy transmission of other infrared lasers.
