Imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. In a new study, researchers report using an “air waveguide” to enhance light signals collected from distant sources; the waveguides could have many applications, including long-range laser communications, detecting pollution in the atmosphere, making high-resolution topographic maps and laser weapons. College Park, MD (PRWEB) July 22, 2014 Imagine being able to...

Kyoto, Japan, Oct 15, 2013 - (ACN Newswire) - On October 16, Shimadzu Corporation will launch the new customizable 'LA series' of planar diffraction gratings for laser systems. Diffraction grating elements for 633 nm to 1064 nm waveband with 1600 lines/mm, exhibit a diffraction efficiency of 98% - the highest in this category of technology. This feature is important for expansion and compression of laser pulses for light sources used in laser processing. The gratings can also be used in...

There are several ways to "trap" a beam of light — usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications. The new system, devised through computer modeling and then demonstrated experimentally, pits light waves against light waves: It sets up two waves that have the same wavelength, but exactly opposite phases...

Device For Portable, Ultra-precise Clocks And Quantum Sensors Developed By Scientists
2013-05-09 10:59:35

University of Strathclyde In a joint project between the Universities of Strathclyde and Glasgow, Imperial College London and the National Physical Laboratory, researchers have developed a portable way to produce ultracold atoms for quantum technology and quantum information processing. Their research has been published in the journal Nature Nanotechnology, where it is featured on the front cover. Many of the most accurate measurement devices, including atomic clocks, work by...

The precise methodology of Richard Feynman's famous double-slit thought-experiment — a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave — has been followed in full for the very first time. Although the particle-wave duality of electrons has been demonstrated in a number of different ways since Feynman popularized the idea in 1965, none of the experiments have managed to fully replicate the methodology set out in Volume 3 of...

Atom Optics To Predict Gravitational Waves

[ Watch the Video: Atomic Interferometer To Predict Gravitational Waves ] April Flowers for redOrbit.com - Your Universe Online NASA is pursuing a pioneering technology capable of atomic-level precision to detect gravitational waves or ripples in space-time caused by cataclysmic events, including the Big Bang itself. Researchers at NASA's Goddard Space Flight Center, AOSense, Inc and Stanford University have been awarded funding under NASA's Innovative Advanced Concepts (NIAC)...

Wave Properties of Individual Heavy Molecules Can Also Be Observed Experimentally/Video Shows Development of Interference Pattern in (Nearly) Real Time Quantum theory describes the world of atoms very precisely. Still, it defies our macroscopic conception of everyday´s world due to its many anti-intuitive predictions. The wave-particle dualism probably is the best known example and means that matter may spread and interfere like waves. Now, an international team of researchers has...

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behavior — in conflict with our everyday ideas of what is real or local. An international team of scientists now succeeded in shooting a movie which shows the build-up of a matter-wave interference pattern from single dye molecules which is so large (up to 0.1 mm) that you can easily see it with a camera. This visualizes the...

Researchers Bend Radio Waves Into Pasta Shapes
2012-03-02 13:36:50

Researchers have solved the problem of radio congestion by twisting radio waves into the shape of fusilli pasta. Scientists reported in the Institute of Physics and German Physical Society's New Journal of Physics that this feat allows for a potentially infinite number of channels to be broadcast and received. A wave is able to twist a certain number of times in either a clockwise or anti-clockwise direction, allowing for several configurations. "In a three-dimensional perspective,...

Seismology
2014-01-12 00:00:00

Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

Doppler Effect -- The Doppler effect is the apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from both motion of the source and motion of the observer. Each of these effects is analyzed...
