Using air to deflect lasers
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary.....»»
Ultrasonic Holograms: Who Knew Acoustics Could Go 3D?
Imaging and other medical applications waiting in the wings Although its origins trace back to the 1960s and ‘70s, acoustic holography as a field has been hampered by rampant noise created by widespread reflection and scattering. (Lasers.....»»
New ink jet approach offers simple way to print microdisk lasers for biosensing
Researchers have developed a unique inkjet printing method for fabricating tiny biocompatible polymer microdisk lasers for biosensing applications. The approach enables production of both the laser and sensor in a room temperature, open-air environme.....»»
Zapping quantum materials with lasers tells us how atoms relate
Phase transitions are a fundamental piece of physics and chemistry. We're all familiar with different phases of water, for example, but this idea of a system of particles changing what it looks like and how it behaves is really ubiquitous in science......»»
A vacuum-ultraviolet laser with submicrometer spot for spatially resolved photoemission spectroscopy
If vacuum ultraviolet lasers can be focused into a small beam spot, it will allow investigation of mesoscopic materials and structures and enable the manufacture of nano-objects with excellent precision. Towards this goal, Scientist in China invented.....»»

Lasers create miniature robots from bubbles
Robots are widely used to build cars, paint airplanes and sew clothing in factories, but the assembly of microscopic components, such as those for biomedical applications, has not yet been automated. Lasers could be the solution. Now, researchers rep.....»»
Scientists use diamonds to generate better accelerator beams
Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce operation cost......»»
Optical data transmission speed increased by a factor of at least 10,000
Pulsed lasers repeatedly emit light for a short period of time as if blinking. They have the advantage of focusing more energy than a continuous wave laser, whose intensity is kept unchanged over time. If digital signals are loaded in a pulsed laser,.....»»
Clocking electron movements inside an atom
Hard X-ray free-electron lasers (XFELs) have delivered intense, ultrashort X-ray pulses for over a decade. One of the most promising applications of XFELs is in biology, where researchers can capture images down to the atomic scale even before the ra.....»»
Lasers and molecular tethers create perfectly patterned platforms for tissue engineering
Imagine going to a surgeon to have a diseased or injured organ switched out for a fully functional, laboratory-grown replacement. This remains science fiction and not reality because researchers today struggle to organize cells into the complex 3-D a.....»»
A curious observer’s guide to quantum mechanics, pt. 2: The particle melting pot
In which lasers do things that make absolutely no sense but give us great clocks. One of the quietest revolutions of our current century has been the entry of quantum mechanics into our everyday technology. It used to be that quantum ef.....»»
Hisense’s TriChroma Laser TV produces an insane amount of colors
Hisense has broken through a barrier with its new TriChroma Laser TV, which can produce more colors than regular TVs, thanks to red, green, and blue lasers......»»
Material for future electronics: New method makes graphene nanoribbons easier to produce
Russian researchers have proposed a new method for synthesizing high-quality graphene nanoribbons—a material with potential for applications in flexible electronics, solar cells, LEDs, lasers, and more. Presented in The Journal of Physical Chemistr.....»»
New type of atomic clock could help scientists detect dark matter and study gravity"s effect on time
Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. The best atomic clocks.....»»
