Abstract

A beam-homogenizing device consisting of a short tip of silver-halide infrared fiber eliminates the low-order multimode effect generated by bending of hollow guides. A series of experiments with a CO₂ laser shows that the solid fiber functions as a homogenizer with a small insertion loss of 0.2 dB.
