Fiber laser manufacturer Nufern of East Granby, Conn., has been awarded multiple contracts on competitively bid programs to build 46 >1-kW fiber amplifiers in support of multiple government laser efforts. The amplifiers, to be delivered later this year, will be used to develop and test coherent optical phased array and spectrally combined array technologies that enable scalable laser weapons 10 times lighter and more compact than existing high-power chemical laser systems. The systems could perform laser radar, target designation, tactical and self-protection tasks.
