Laser Weapon in the Works for Ground Vehicles
ARLINGTON, Va., June 12, 2014 — The first laser weapons will soon be implemented on U.S. Navy ships. And now, the Marines plan to follow suit. The Office of Naval Research, in conjunction with researchers from the Naval Surface Warfare Center–Dahlgren Division, are working to create a solid-state laser that can ultimately prevent enemy unmanned aerial vehicles from tracking and targeting Marines on the ground. Developed under the Ground-Based Air Defense Directed Energy On-the-Move program (GBAD), this will

Optical Invisibility Cloak Ideal for Diffusive Media
KARLSRUHE, Germany, June 9, 2014 — A new invisibility cloak technology conceals objects in diffusive media such as fog, clouds or frosted glass. Optical cloaks have been challenging to achieve for all situations; most only work at specific colors or polarizations, or from very...
Harmonic Generation Promising for Powerful Light Source
MANHATTAN, Kan., June 6, 2014 — A new approach to harmonic generation aims to create smaller, more powerful tabletop light sources for laboratory research, particularly in the emerging area of strong-field physics. “High-order harmonic generation has been considered a very...
New Terahertz System Simpler, Clearer
EVANSTON, Ill., June 6, 2014 — Biosensing, space research and the ability to see through opaque surfaces without x-rays are all enabled by terahertz radiation. However, such systems have long been elusive. A team from Northwestern University has produced terahertz radiation in a...
Photo-Induced Doping Tames Graphene
BERKELEY, Calif, June 6, 2014 — Doping graphene with boron nitride may be a way to tame the material, introducing a bandgap and making it useful in electronic devices. However, controlling the electrical properties of graphene boron nitride (GBN) heterostructures has been tricky....
Spectroscopy Helps Capture Charge Transfer in Solar Cells
OLDENBURG, Germany, MODENA, Italy, and MILAN, June 6, 2014 — Ultrafast spectroscopy has allowed physicists, for the first time, to observe and capture the light-to-current conversion process in an organic solar cell as it happens. The quantum-mechanical nature of electrons and their coupling to nuclei is...
Lamda Guard, Airbus Collaborate on Laser Shield
HALIFAX, Nova Scotia, Canada, June 5, 2014 — Lamda Guard Inc. has teamed up with Airbus SAS to test a metamaterial system designed to deflect bright light and laser beams directed at jetliners. Lamda Guard develops thin-films coatings that, when applied to aircraft windows, selectively block...
Night Vision, Laser Imaging Enhance Lymphatic Studies
HOUSTON, June 5, 2014 — Better imaging of the lymphatic system is now possible using IR techniques, allowing earlier detection of cancer and lymphedema. It could also lead to more effective, manageable treatment of such diseases. A new technology, developed by a team from...
Light Mitigates Alzheimer’s Symptoms
TROY, N.Y., June 4, 2014 — Those suffering from Alzheimer's disease and dementia could soon find some relief thanks to a developing light treatment. A new study by researchers at Rensselaer Polytechnic Institute shows that daytime light treatment could improve sleep and...
MRI-guided Laser an Alternative to Epilepsy Surgery
ATLANTA, June 4, 2014 — Many patients suffering from certain types of epilepsy find little relief or control by way of medications. Now there may be a new solution. A team from Emory University School of Medicine has developed an MRI-guided, minimally invasive laser...
UV Light Sets Crystals in Motion
SINGAPORE, June 3, 2014 — Tiny crystals of a cobalt coordination compound leap, twirl and burst apart like popcorn when exposed to UV light. A team led by researchers at the National University of Singapore suggests the microscopic phenomenon could find macroscopic...
4 Photonics Projects Get Defense Funding
WASHINGTON, June 3, 2014 — The U.S. Department of Defense has awarded funding totaling $28.3 million for four photonics graduate research projects under its Multidisciplinary University Research Initiative (MURI). Brief summaries of the projects follow. For further...
