For delivery of high-power IR laser light, hollow-core fibers have advantages of ruggedness, environmental stability, and high-power threshold over the IR solid-core fibers, such as fluoride glasses, metal halides, and chalcogenides fibers. In this paper, we focus on the hollow-fiber beam delivery system for high power mid-IR lasers with more than 1-kW cw power or 1000 mJ pulse energy and review the current status of hollow fibers by showing the system designs and the tested results.
