IR-transmitting fibers fabricated at the Naval Research Laboratory (NRL) have low optical loss (tilde 0.2 dB/m) and have been successfully used in aircraft missile defense system demonstrations for the 2 to 5 micrometer region to replace bulk optics connecting the laser to the jam head as well as being 'wired' inside the jam head. These conventional, solid-core fibers result in significant weight reduction. They reduce system size and complexity as well as cost of both installation and maintenance, and are capable of laser power input typical of current systems. However, advanced infrared threats require much higher laser power, which these solid-core fibers cannot tolerate.
