To study hollow waveguides for CO2 laser transmission,a liquid-phase deposition technique is applied to form a silver film inside silica capillary based on the method of silver mirror reaction.Using this fabrication method,the optimum combination of different parameters is gained and hollow waveguides have been made successfully with a bore size of 1mm and a guide with length of as long as 2m on self-producing apparatus.To meet quality silver film,a relative high temperature,low flowing speed and long time are adopted on the basis of low reactant concentration.The maximum transmission efficiency of hollow-core fiber without dielectric coating can be up to 85 percent and loss can be low to 0.5dB/m,maximum output power is 53W for stable 20mintues.
