Optics: Statistics light the way
Millions of years of evolution have molded our eyes into highly sensitive optical detectors, surpassing even many man-made devices. Now, Leonid Krivitsky and his co-workers at the A*STAR Data Storage Institute ...

Improving our understanding of the human brain, gathering insights into the origin of our universe through the detection of gravitational waves, or optimizing the precision of GPS systems- all are difficult challenges to ...
(Phys.org) —An international team of researchers succeeds in generating flashes of extreme ultraviolet radiation via the reflection from a mirror that moves close to the speed of light.
An optics innovation by a University of Sydney researcher has been a financial and technology transfer success story creating a wave of sales for Finisar, the Australian company that has used the new technology.
(Phys.org) —A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes ...
(Phys.org) —Researchers at the Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used ...
(Phys.org) —SLAC researchers have demonstrated for the first time how to produce pairs of X-ray laser pulses in slightly different wavelengths, or colors, with finely adjustable intervals between them – ...
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient ...
(Phys.org) —The founding father of DNA nanotechnology – a field that forges tiny geometric building blocks from DNA strands – recently came to SLAC to get a new view of these creations using powerful ...
(Phys.org)—With SLAC's Linac Coherent Light Source X-ray laser, timing is everything. Its pulses are designed to explore atomic-scale processes that are measured in femtoseconds, or quadrillionths of a ...
One-billionth of a billionth of a second. That's the scale – an attosecond – at which scientists seek to image and control electronic motion in matter. Its natural time scale.
LANL researchers and collaborators have made the first demonstration of rapidly switching on and off "slow light" in specially designed metamaterials at room temperature. Metamaterials are assemblies of ...
(Phys.org)—The way electrons move within and between molecules, transferring energy as they go, plays an important role in many chemical and biological processes, such as the conversion of sunlight to energy ...
The fact that an ultrashort laser pulse is capable of demagnetizing a ferromagnetic layer in a jiffy has been well-known since approximately 1996. What we don't yet understand, however, is how exactly this demagnetization ...
A new photodetector can cleanly discriminate among four states, not just the standard two states of binary logic.
