31 May 2013 Thermal and vibration testing of ruggedized IR-transmitting fiber cables
Author Affiliations +
We present successful results obtained for thermal/ vibration testing of ruggedized, IR-transmitting chalcogenide glass fiber cables using a government facility with state-of-the-art equipment capable of MIL-SPEC environmental testing. We will also present results of a direct imprinting process to create novel “moth eye” patterned surfaces on the IR fiber cable ends that significantly reduces endface reflection losses from 17% to less than 3%. The cables with these imprinted “moth eye” ends transmit much higher IR laser power without damage than was obtained for previous cables with traditional AR coatings.
