A curious thing happened when MIT researchers Adam Vernon and Ronald Garcia Ruiz, along an international team of scientists, recently performed an experiment in which a sensitive laser spectroscopy te...
Cornell engineers used precisely timed laser pulses to control changeable properties in a quantum material, pioneering a method that may have wide applications across a class of materials with immense...
There’s nothing new thing under the sun — except maybe light itself.Over the last decade, applied physicists have developed nanostructured materials that can produce completely new states of light exh...

New laser design more inexpensive multi-color output
2017/7/24
From checkout counters at supermarkets to light shows at concerts, lasers are everywhere, and they’re a much more efficient light source than incandescent bulbs. But they’re not cheap to produce.A new...
1 billion suns:World’s brightest laser sparks new behavior in light
1 billion suns World’s brightest laser sparks in light
2017/7/24
By focusing laser light to a brightness 1 billion times greater than the surface of the sun — the brightest light ever produced on Earth — the physicists have observed changes in a vision-enabling int...

Researchers at the University of California San Diego have demonstrated the world’s first laser based on an unconventional wave physics phenomenon called bound states in the continuum. The technology ...
SEGMENTATION BASED ROBUST INTERPOLATION – A NEW APPROACH TO LASER DATA FILTERING
Laser scanning Filtering Segmentation
2015/8/13
a general strategies for solving the problem – for filtering can be identified. The first work directly on the measured points and
geometric criteria are used for the decision, if a point is on the g...
A NEW APPROACH TO AUTOMATIC JUNCTION OF OVERLAPPING AERIAL IMAGERY DATA
Automation matching recognition, detection
2015/6/1
The original approach to image matching is proposed. The method itself can be classified as relational matching, bases on point
features. For robust extraction and filtration of features the special...

New resonant cavity-enhanced absorber structures for mid-infrared detector application
Optical resonant cavity Photodetectors HgCdTe Gratings
2012/4/19
A new dielectric Fabry-Perot cavity was designed for a resonant enhancing optical absorption by a thin absorber layer embedded into the cavity. In this cavity, the front mirror is a subwavelength grat...
A New Artificial Dielectric Metamaterial and its Application as a THz Anti-Reflection Coating
Artificial Dielectric Metamaterial THz Anti-Reflection Coating Optics

Progress in calculating the spectrum of excited baryons and mesons in lattice QCD is described. Correlation matrices of sets of spatially-extended hadron operators have been studied and their effectiv...
A New Entropic Force Scenario and Holographic Thermodynamics
Entropic Force Scenario Holographic Thermodynamics
2010/12/21
We propose a new holographic program of gravity in which we introduce a surface stress tensor.
Our proposal differs from Verlinde’s in several aspects. First, we use an open or a closed screen, a tem...
