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

U.S. Naval Research Laboratory ‘connects the dots’ for quantum networks

WASHINGTON — Researchers at the U.S. Naval Research Laboratory (NRL) developed a new technique that could enable future advancements in quantum technology.

The technique squeezes quantum dots, tiny particles made of thousands of atoms, to emit single photons (individual particles of light) with precisely the same color and with positions that can be less than a millionth of a meter apart. More

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.
