A possible strategy for a tabletop chiral attosecond laser
When molecules form from many atoms, the atoms can combine in different ways. Two forms of the same molecule can have the same composition but have different arrangements of atoms, giving rise to isomers. Some isomers may have structures that are mir.....»»
Creating "ghostly mirrors" for high-power lasers
Laser-driven 'mirrors' capable of reflecting or manipulating light have been produced in research led at the University of Strathclyde......»»
Make That Laser Cutter Blaze: Upgrade a K40

Using ultrafast laser flashes to generate and measure the shortest electron pulse to date
By using ultrafast laser flashes, scientists at the University of Rostock in collaboration with researchers of the Max Planck Institute for Solid State Research in Stuttgart have generated and measured the shortest electron pulse to date. The electro.....»»
Building off the "anti-laser," researchers create a device that directs waves
Building off a breakthrough "anti-laser," a team of researchers has developed a system that can direct light and other electromagnetic waves for signal processing without any unwanted signal reflections—an innovation that could advance local area n.....»»
Scientists tweak synthesis of high-entropy carbides for better efficiency
Researchers from Skoltech and Tomsk Polytechnic University have tuned the synthesis of a five-element carbide—a strong, hard-melting compound of carbon and five transition metals—which holds much promise for industrial ceramics and catalysis......»»
GHz burst mode femtosecond laser pulses can create unique two-dimensional periodic surface nanostructures
Scientists working on laser application at the RIKEN Center for Advanced Photonics (RAP) have demonstrated that GHz burst mode femtosecond laser pulses can create unique two-dimensional (2D) laser-induced periodic surface structures (LIPSS) on silico.....»»
Climate change is threatening Madagascar"s famous forests: Study shows how serious it is
Global climate change doesn't only cause the melting of polar ice caps, rising sea levels and extreme weather events. It also has a direct effect on many tropical habitats and the animals and plants that inhabit them. As fossil fuel emissions continu.....»»
Nearly 50-meter laser experiment sets record in University of Maryland hallway
It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that's what happened in UMD's Energy Research Facility, an unremarkable looking building on the northeast corner of campus. If.....»»
