  1. Pentagon Developing Laser-Shooting Drones To Intercept Enemy Missiles

    The U.S. Missile Defense Agency (MDA) is proposing to spend $66 million on a program to develop and deploy unmanned aerial vehicles (UAV) that fire lasers at intercontinental ballistic missiles (ICBMs) shortly after takeoff, or during their boost phase of flight, when they are most vulnerable.

  2. Seeing Optical Parametric Oscillators In A New Light

    Stanford researchers have bucked standard guidelines to retool a formerly finicky device to shoot ultrafast light pulses useful in remote sensing and diagnostic applications.

  3. Injector Gun, Cryomodule Delivered For SLAC's X-Ray Laser Upgrade

    The injector gun and first cryomodule for Linac Coherent Light Source II (LCLS-II) — one of the most advanced superconducting laser projects in the world and the only one in the U.S. — have arrived at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory in Menlo Park, California. 

  4. Chinese Scientists Develop World's First All-Silicon Laser

    Scientists at Fudan University in Shanghai, China, have demonstrated the world's first optically pumped all-silicon distributed-feedback (DFB) laser, a key achievement toward realizing possibilities in integrated silicon photonics.

  5. First Observation Of Accelerating Beams In Curved Space

    Physicists report the first experimental observation of accelerating light beams in curved space. This phenomenon provides new ideas for emulating Einstein's general relativity, as well as new ways of propagating light in curved surfaces and media.

  6. Unique Topological Phenomena In An Open System Of Photonic Crystals

    Scientists at Massachusetts Institute of Technology (MIT) have observed two distinct topological effects in an open system of photonic crystals. Such phenomena open new possibilities in making novel light-based computing systems or light-emitting devices.

  7. NASA Piggybacks Spectrograph On Comm Satellite To Study Ionosphere’s RF Disruption

    The National Aeronautics and Space Administration (NASA) is set to launch its Global-scale Observations of the Limb and Disk (GOLD) mission to study Earth's near-space environment and better understand what disrupts radio signals and satellites used for communications and the Global Positioning System (GPS) for radio navigation.

  8. Harvard-Produced Metalens Is “Next Big Step” In Optics, Virtual Reality

    Scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have built the first single lens that can focus the entire visible spectrum of light. The breakthrough means bulky stacked lenses could soon be replaced with simpler, flat metalenses — without loss of resolution.

  9. Rice Scientists Find New Kind Of Quantum Material: The Weyl-Kondo Semimetal

    Scientists at Rice University and the Vienna University of Technology in Austria, who have been researching high-temperature superconductivity, have stumbled across a new type of quantum material they call a “Weyl-Kondo semimetal.” It exhibits theoretical properties found in disparate materials, such as topological insulators, heavy fermion metals, and high-temperature superconductors.

  10. Hollow Optical Antennas For Superior Photon Creation And Control

    Scientists at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, have introduced a novel plasmonic cavity antenna design that enhances the creation and control of photons emitted by atoms and molecules.
