This article reports on the results of free electron laser (FEL) power transmission measurements through chalcogenide fibers. The FEL power transmission was tested by two types of chalcogenaide NSEG fibers, a normal fiber and a tapered fiber, made by varying the drawing speed from 2 to 17 cm/min. As a result, the tapered NSEG fiber is able to transmit 5–7 μm FEL power with a 10 MW/micropulse without surface damage. Tapered NSEG fibers are useful, therefore, for power transmission to narrow spaces such as the slide glass between the stage and the objective lens in a microscope. © 1997 American Institute of Physics.
