Lockheed Martin Demonstrates Hi-Power Electric Fiber-Laser

Lockheed Martin has demonstrated the feasibility of generating 30-kilowatt electric fiber laser, the highest power ever documented while retaining beam quality and electrical efficiency. The successful demonstration marks a significant milestone on the path to deploying a mission-relevant laser weapon system for a wide range of air, land and sea military platforms. “The high-energy laser serves as the heart of a laser weapon system,” said Dr. Johnson. “This 30-kilowatt milestone shows our commitment to producing the high beam quality and high power needed to address a variety of military ‘speed-of-light’ defensive operations.”

Prior laser weapon demonstrations in the industry showed target acquisition, tracking and destruction. However, these solutions were limited for tactical military use because their laser inefficiencies drove significant size, power and cooling needs not readily supported by key military ground and airborne platforms. The laser demonstrated by Lockheed Martin’s scientists combined multiple sources of high power lasers, into a single, near-perfect quality beam of light – all while using approximately 50 percent less electricity than alternative solid-state laser technologies. This unique process, called ‘Spectral Beam Combining‘, sends beams from multiple fiber laser modules, each with a unique wavelength, into a combiner that forms a single, powerful, high quality beam.

“Lockheed Martin has opened the aperture for high power, electrically driven laser systems suitable for military applications,” said Dr. Ray O. Johnson, senior vice president and chief technology officer of Lockheed Martin. “Advancements in available laser components, along with the maturity and quality of our innovative beam-combining technology, support our goal of providing lightweight and rugged laser weapon systems for use on military platforms such as aircraft, helicopters, ships and trucks.”

Lockheed Martin has specialized in directed energy laser weapon system development for the past 30 years and purchased Aculight in 2008 to further strengthen its offerings at every level – from expert advice and pioneering research to solid prototyping and flexible manufacturing.
