Researchers Use Nano-Particles to Increase Power, Improve Eye Safety of Fiber Lasers

WASHINGTON — Scientists at the U.S. Naval Research Laboratory have devised a new process for using nano-particles to build powerful lasers that are more efficient and safer for your eyes.

They’re doing it with what’s called “rare-earth-ion-doped fiber.” Put simply, it’s laser light pumping a silica fiber that has been infused with rare earth ions of holmium. According to Jas S. Sanghera, who heads the Optical Materials and Devices Branch, they have achieved an 85 percent efficiency with their new process. More

NRL, AFRL Develop Direct-Write Quantum Calligraphy in Monolayer Semiconductors

Scientists at the U.S. Naval Research Laboratory (NRL) and the Air Force Research Laboratory (AFRL) have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer semiconductors such as tungsten diselenide (WSe2). Single photon emitters (SPEs), or quantum emitters, are key components in a wide range of nascent quantum-based technologies, including computing, secure communications, sensing and metrology. More

NRL Researcher Awarded as Part of a Team Saving Marine Corps Millions

Dr. Marriner Merrill, a research scientist at the U.S. Naval Research Laboratory, was recognized as part of a team that received the Navy "Innovation Excellence Acquisition Team of the Year Award" for demonstrated engineering ingenuity in developing a repair solution for delaminated transparent armor, estimated to save the Marine Corps $105 million.

NRL Research Paves Way Toward Development of New Monolayer Materials

Scientists at the U.S. Naval Research Laboratory (NRL) have discovered the reason for the large variations observed in the optical properties of new single monolayer semiconductors such as tungsten disulphide (WS2). Single monolayer transition metal dichalcogenides (TMDs), such as WS2, are an emerging class of materials that exhibit many promising optoelectronic properties, with the potential for future device applications.

Transparent Armor

Spinel is actually a mineral, it's magnesium aluminate, says Dr. Jas Sanghera, who leads the research. The advantage is it's so much tougher, stronger, harder than glass. It provides better protection in more hostile environments—so it can withstand sand and rain erosion.

Dr. Brian L. Justus, head of the U.S. Naval Research Laboratory's Optical Physics Branch, was elected a NAI Fellow on Dec. 12, 2017, and will be inducted into the National Academy of Inventors during the Seventh Annual NAI Conference on April 5 in Washington, D.C. More

Materials Research Team Lights the Way for More Efficient LEDs

WASHINGTON — Researchers at the U.S Naval Research Laboratory (NRL) Center for Computational Materials Science, working with an international team of physicists, have revealed that nanocrystals made of cesium lead halide perovskites (CsPbX3), is the first discovered material which the ground exciton state is "bright,” More

NRL Improves Optical Efficiency in Nanophotonic Devices

WASHINGTON — A team of physicists, headed by the U.S. Naval Research Laboratory (NRL), have demonstrated the means to improve the optical loss characteristics and transmission efficiency of hexagonal boron nitride devices, enabling very small lasers and nanoscale optics. More
