A hollow light guideusing the aluminum-phosphor bronze reflector to transmit UV laser beams has been studied.The delivery characteristics of the hollow light guide with different bending angle havebeen studied using XeCl excimer laser. The transmission of straight light guide was 72%/mand the transmission of bending wave guide of different radius of curvature have also beenmeasured. The measurement showed that the transmission was proportional inversely to thebending radius R. Some methods to improve the transmission have been proposed. Theexperiment showed that helium gas displayed the weakest absorption and can improve thetransmittance of hollow light guide. When the light beams with very small divergencepropagate as whispering gallery modes, which propagate through the guide by successivereflections from the outer wall only , the transmission is independent of the curvature R.
