High power, high intensity CO infrared laser transmission through As2S3glass fibers

摘要

Optical power transmission of 5hyphen;mgr;m band CO laser beam through As2S3glass core Teflon fluorinated ethylene propylene clad fibers is described. The maximum transmitted power is as high as 62 W with a 700hyphen;mgr;m core diameter fiber, which corresponds to a power intensity of 16 kW/cm2at the fiber output end. The influence of fiber bending on the transmission characteristics is also reported.
