Hollow waveguides are an attractive alternative to conventional solid-core IR fibers. The hollow core structure is well suited for the transmission of high laser powers as well as for some broadband sensor applications such as gas sensing and radiometry. Over the past 15 years a variety of fabrication techniques and hollow configurations have been studied. Today losses for these unique guides are as low as 0.1 dB/m and laser powers as high as 2.7 kW have been transmitted. In this paper we review the current status of hollow waveguides and indicate some of the most promising applications for this technology.
