REDONDO BEACH, Calif., Oct. 15, 2008 -- Northrop Grumman Corporation (NYSE:NOC) has been chosen to develop single-frequency fiber amplifiers for the new Revolution in Fiber Lasers (RIFL) program by the Defense Advanced Research Projects Agency (DARPA).

The RIFL program takes a similar approach to maturing fiber laser technology as Northrop Grumman demonstrated for solid-state lasers through support from U.S. military services and government agencies -- by designing the building blocks needed to combine laser beams that can be scaled to a weapons-class power level while maintaining good beam quality.

Fiber lasers are 1.5 to 2 times more efficient than solid-state lasers, delivering more laser power per weight and volume. High beam quality and efficiency make fiber laser technology, intrinsically, ideal to pursue in parallel with solid-state lasers, the company noted.

"We'll build on internal successes demonstrating the ability to scale and operate single frequency fibers at high powers," said Dan Wildt, vice president of Directed Energy Systems for Northrop Grumman's Space Technology sector. "Coupled with the proprietary scalable architecture that we've successfully developed for the Joint High Power Solid State Laser program, we have demonstrated the essential building blocks for success. RIFL will enable us to scale this important technology to weapons-class powers."

Northrop Grumman has previously scaled narrow band fiber lasers to powers of 400 W by combining multiple fiber amplifiers with a near perfect beam quality of 1.1.

Northrop Grumman received a $4.5 million, 15-month contract for Phase I, with an option for a $4.6 million, 18-month Phase II contract. Key goals of the DARPA contract are demonstration of single frequency fiber amplifiers at 1kW in the 15-month first phase and 3kW at the end of the 18-month second phase.

Single frequency fiber lasers and amplifiers are now typically limited to several hundred watts by an effect known as Stimulated Brillouin Scattering (SBS), which reflects power backwards and damages low-power components. The Northrop Grumman-led team will use proven proprietary approaches to eliminate SBS and achieve the program's goals.

Northrop Grumman Corporation is a global defense and technology company whose 120,000 employees provide innovative systems, products, and solutions in information and services, electronics, aerospace and shipbuilding to government and commercial customers worldwide.
