Hollow glass waveguides are used to deliver free electron laser (FEL) energy for applications in medicine and laser surgery. The hollow guides, optimized for the delivery of 6.45-mm FEL radiation, exhibited losses for the 1000-mm bore as low as 0.39 dBym when the guide was straight and 1.75 dBym when bent to a radius of 25 cm. Hollow glass guides are flexible, and their broadband capability provides an ideal fiber optic for the tunable FEL.
